To ablate tumor tissues safely and efficiently occupy a high priority in physical cancer therapy. However, it is still a challenge to realize high conversion efficiency of photothermal reagents and multi-functions with low health risks. Herein, nano-heterostructure membrane was synthesized by composting MoSe 2 :Nd nanosheets and graphene nanoflakes for improving the therapy efficiency and efficacy. It not only exerts fulfilling photothermal behaviors under 808 nm laser excitation, but also exhibits outstanding laser-induced photodynamic performance due to photogenerated carriers transfer from unique physical heterostructure. With bimodal photothermal/photodynamic therapy potential, the heterojunction structure is incorporated into the polydimethylsiloxane (PDMS) film and subcutaneously implanted into animate bodies, which further facilitate biomedical safety and experiment operability in tumor treatments, cutting off the possible risks arising from direct injection. In vitro photothermal properties and biomedical experiments strongly proof the composite film can exert intense photothermal response at laser excitation and possess considerably satisfactory biocompatibility, effectively eliminating tumor tissues without undesirable damage and pathological changes to normal organs.

Narrow-band red-emitting fluoride phosphors play a crucial role in lighting and backlight displays, whereas the stability issue is a major challenge. Here, highly stable K 2 SiF 6 :Mn 4+ (KSFM) single crystal phosphors with tunable sizes (20–1000 µ m) are grown by a facile saturated crystallization method. The small specific surface area together with the unique Mn 4+ -rare interface layer in KSFM single crystals enables the simultaneous fulfillment of high external quantum efficiency, excellent moisture, improved thermal quenching, and dissipation for high-power and laser-driven lighting applications. As a prototype, a warm white laser diode device with a high luminous flux of 202.7 lm and correlated color temperature of 3277 K, as well as a color rendering index of 87.9 is presented. This work provides new insights into the development of highly efficient and stable materials for advanced lighting applications.

Inspired by common patterns of biological movement, a series of near-infrared (NIR) laser-driven bionic intelligent hydrogel actuators were successfully fabricated via the combination of infiltration method (entirety infiltration and locality infiltration), structure design and material characteristics. The controllable distribution of graphene oxide (GO) particles in a hydrogel matrix resulting from the infiltration method led to abundant bionic deformations with multiple degrees of freedom and flexibility. In addition to the highest response speed of 187.7°/s, the hydrogel actuators underwent accurate and repeatable static deformations and efficient and stabilized dynamic locomotion, demonstrated, for example, through the assembly of origami, the deformation of fingers and palm, the closing and blooming of a chrysanthemum and the crawling of an inchworm. This study opens a new path for practical bionic applications of NIR-triggered hydrogel actuators in self-assembly biosensor, targeted drug delivery and minimally invasive surgery.

Laser-driven phosphor-converted lighting and display technologies offer exceptional energy efficiency and superior performance. However, the development of high-quality white light sources with both excellent color rendering and high brightness remains a significant challenge due to the scarcity of red-emitting color converters that maintain high efficiency and stability under high laser powder densities. In this study, (Sr, Ca)AlSiN 3 : Eu 2+ (SCASN:Eu) phosphor-in-glass films (PiGFs), emitting from 610 to 680 nm, are fabricated on Al 2 O 3 ceramic substrates with minimal interfacial reactions. All PiGFs exhibited excellent densification and maintained high IQE, losses in IQE remaining below 10 % relative to the original phosphor. Notably, the PiGF with an emission peak at 653 nm achieved a lumen density of 206 lm mm −2 @ 23.6 W mm −2 due to its high thermal conductivity (22 W m −1 K −1 ) and low IQE loss. Under rotating excitation, it reached a record 786 lm mm −2 @ 90.6 W mm −2 . Furthermore, a spatially separated YAGG:Ce-CASN:Eu “phosphor wheel” in reflective mode produced a luminous flux of 1125 lm @ 23.6 W mm −2 , a correlated color temperature (CCT) of 6653 K, a color rendering index (CRI) of 86, and CIE coordinates (0.308, 0.338), enabling long-distance illumination and projection display. This work offers a promising strategy for developing high-efficiency color converters for advanced laser-based lighting and display applications.

Although blue laser-excited phosphor-in-glass films (PiGFs) have been extensively investigated for laser-driven display applications, their performance is still constrained due to a broad red emitting spectrum and thermal management challenges, etc. To overcome these limitations, this study develops a novel composite architecture – YAG: Ce transparent ceramic-CsPbBr 1.5 I 1.5 quantum dots (CPBI QDs) in glass film enhanced with h-BN (YAG: Ce TC-QiGF BN). YAG: Ce TC acts as a high thermal conductivity substrate and yellow light component, while QiGF enables to produce narrowband red emission. The h-BN particles are dispersed within QiGF, where a significant portion of them accumulate around the CPBI QDs powders. The inclusion of h-BN significantly improves both light extraction efficiency and thermal conductivity, leading to an increase of blue-light absorption efficiency from 57.74% to 69.26% and mitigation of heat accumulation induced by high-power laser irradiation. Among the three designed prototype projection display systems (YAG: Ce TC, YAG: Ce TC- CASN: Eu PiGF, and YAG: Ce TC-QiGF BN), the YAG: Ce TC-QiGF BN-based configuration demonstrates the most effective red-light enhancement and superior color rendering performance, particularly exhibiting the purest red color due to its narrowband emission feature. This innovative material holds considerable potential for the next-generation laser-driven displays.

High-power broadband near-infrared (NIR) light sources based on laser-excited phosphors are highly desirable for photonics applications in night vision, biomedical imaging and sensing; however, the inherent energy gap law poses a great challenge for the development of efficient NIR luminescent materials. Herein we report a translucent MgO:Cr 3+ ceramic fabricated by spark plasma sintering, which exhibits a broadband NIR emission peak at 810 nm, with an external quantum efficiency of 81% and ultra-high thermal conductivity of 52 W m –1 K –1 . When pumped with a blue laser, the MgO:Cr 3+ ceramic provides an output power exceeding 6 W with a light conversion efficiency of 29%. This laser-driven broadband NIR light source makes it possible to perform NIR imaging with a spatial resolution of 6 lp mm –1 , and is a promising technology for emerging imaging applications.

Up-to-date laser-driven lightings confront a challenge of simultaneously achieving good photometric and chromatic performances. Herein, the coupling of “patterned package design” and “phosphor wheel” was proposed and demonstrated effectively to deal with this tough issue, based on a new architecture of CaAlSiN 3 :Eu 2+ (CASN:Eu) glass ceramic film (GCF) on Y 3 Al 5 O 12 :Ce 3+ (YAG:Ce) GC plate. The fabricated composite has no interface between the two functional layers and retains the admirable luminescent features from CASN:Eu and YAG:Ce for the microstructural integrity during co-sintering. The studies on laser-microcrystalline interactions reveal that the luminescence saturation is almost determined by thermal quenching for YAG:Ce, but is ascribed to thermal/intensity quenching which are equally crucial for CASN:Eu. Benefiting from the elaborate architecture design, good color chromaticity tunability was obtained, and severe photon reabsorption was reduced. Moreover, accompanied with the rotation induced increase of thermal convection to air and pulse-like excitation, the constructed lighting engine under blue laser driven shows bright white light with luminous flux (LF) higher than 1000 lm, adjustable chromaticity from cool to warm, and improved color rendering index (CRI) approaching to 70.

Laser-driven near-infrared II (NIR-II) light sources comprising luminescent ceramics represent a promising research frontier, yet their development remains constrained by the external quantum efficiency (EQE) and thermal stability bottleneck of current luminescent materials. Herein, we present a non-equivalent cation substitution strategy to fabricate high-efficiency translucent MgO:Ni 2+ , Cr 3+ NIR-II luminescent ceramics. The co-doping of Cr 3+ induces structural distortion at Ni 2+ -occupied octahedral sites, effectively breaking the parity-forbidden d-d transition constraint while enabling efficient energy transfer from Cr 3+ to Ni 2+ . These synergistic effects yield remarkable internal and external quantum efficiencies of 61.06% and 39.69%, respectively. The developed ceramic demonstrates exceptional thermal management capabilities with 31.28 W·m −1 ·K −1 thermal conductivity and 92.11% emission retention at 478 K. When integrated into laser-driven NIR-II light sources, the system achieves record-breaking performance of 214 mW output power under 21.43 W/mm 2 blue laser excitation. Practical demonstrations showcase superior non-destructive imaging capabilities with 5.29 lp/mm spatial resolution and 0.97 contrast ratio. This work establishes a new paradigm for developing high-performance NIR-II light sources in advanced imaging and detection technologies.

Laser-driven white lighting is believed to be a future-oriented high-brightness solid-state light (SSL) source, which is confronted with a severe challenge in developing a laser-driven color converter with efficient thermal management. Herein, a unique architecture of phosphor-in-glass film bonded with a microchannel cooling (PiGF-MC) converter was proposed to enable high luminescence saturation for high-brightness laser-driven white lighting. The PiGF consisted of yellow-emitting Y 3 Al 5 O 12 :Ce 3+ (YAG) was sintered on an alumina substrate and then soldered on a liquid-cooled microchannel radiator, which realizes outstanding heat dissipation performance of laser-driven PiGF. The PiGF-MC converter possesses luminance saturation threshold under a high laser power density of 21 W mm −2 , 2.3 times that of the traditional PiGF-alumina converter (∼9 W mm −2 ). High-brightness laser-driven white light is achieved by the PiGF-MC with a high luminous flux of 2953 lm@21 W mm −2 , and long-term stable optical performance is simultaneously realized. The working temperatures of laser-driven PiGF-MC are all lower than 200 °C under various laser powers. This finding demonstrates the broad prospect of the proposed PiGF-MC converter architecture for next-generation high-brightness laser-driven white lighting.
