The growing demand for color conversion materials in laser projection displays has positioned phosphor-in-glass films (PiGF) as a promising solution. Single-side sapphire-based anti-reflection (AR) and high-reflection (HR) coatings were fabricated via electron beam evaporation on sapphire substrate backsides, involving alternate deposition of Ta 2 O 5 and SiO 2 thin films with varying thicknesses. These coatings significantly enhanced the optical performance of PiGF, improving its suitability for transmissive PiGF devices. The design enhances blue light in the 440–470 nm range, increasing transmittance from 85.5 % to 93.7 %. Visible light (500–700 nm) generated under blue excitation is reflected toward forward emission, boosting sapphire reflectance from 14.2 % to 94.3 %. As a result, excellent optical performance is achieved. In practical tests, the coated sapphire achieves 2770.6 lm at 12.9 W mm −2 and a luminous efficiency (LE) of 213.7 lm·W −1 , representing the 28.6 % improvement over the uncoated β-Sialon:Eu 2+ (β-Sialon) PiGF. This represents the best optical performance of β-Sialon PiGF to date. Building on this, the composite CaAlSiN 3 :Eu 2+ (CASN:Eu) with a color temperature of 6248 K has been developed, paving the way for the commercialization of PiGF composite materials in laser lighting and display applications.

Given that vascular endothelial growth factor (VEGF) and placental growth factor (PIGF), over-expressed in breast cancer cells and M2-like tumor-associated macrophages (M2-TAMs) within tumor microenvironment (TME), work synergistically and independently in mediating tumor progression and immunosuppression, combinatorial immune-based approaches targeting them are expected to be a potent therapeutic modality for patients. Here, polyethylene glycol (PEG) and mannose doubly modified trimethyl chitosan (PEG = MT) along with citraconic anhydride grafted poly (allylamine hydrochloride) (PC)-based nanoparticles (NPs) (PEG = MT/PC NPs) with dual pH-responsiveness were developed to deliver VEGF siRNA (siVEGF)/PIGF siRNA (siPIGF) to both M2-TAMs and breast cancer cells for antitumor immunotherapy. With prolonged blood circulation and intelligent pH-sensitivity, PEG = MT/PC NPs were highly accumulated in tumor tissues and then internalized in M2-TAMs and breast cancer cells via mannose-mediated active targeting and passive targeting, respectively. With the charge-reversal of PC, PEG = MT/PC NPs presented effective endosomal/lysosomal escape and intracellular siRNA release, resulting in efficient gene silencing. Due to the synergism between siVEGF and siPIGF in anti-proliferation of tumor cells and reversal of the TME from pro-oncogenic to anti-tumoral, PEG = MT/PC/siVEGF/siPIGF NPs (PEG = MT/PC/siV-P NPs) exerted robust suppression of breast tumor growth and lung metastasis. This combination strategy may provide a promising alternative for breast cancer therapy.

Phosphor-in-glass (PiG) materials have been widely fabricated into various types of luminescent films due to their simple fabrication process, high color purity, and adjustable luminescence. However, existing reflective PiG films (PiGFs) still face significant challenges in serving as reliable color converters, mainly stemming from inadequate thermal management capabilities and limited optical efficiency. Herein, magnesium oxide (MgO) with a high thermal conductivity of 47–53.5 W/(m·K) was selected to form a MgO-in-glass (MiG) layer aimed at simultaneously enhancing heat dissipation and light extraction. A reflective PiGF@AlN converter with a sandwich structure—Y 3 Al 5 O 12 :Ce 3 + (YAG) PiGF and MiG layer on AlN substrate (YAG@MiG@AlN, YMA)—was developed. This structure effectively leverages the high thermal conductivities of AlN and MgO to improve heat dissipation. The optimized YMA converter with 60 wt% YAG and 4 wt% MgO achieves a high saturation threshold of 29 W/mm 2 and a luminous flux (LF) of 3682 lm, which exhibits a 24 % enhancement in maximum LF over the YAG@TiO 2 @AlN (YTA) converter and a 39 % improvement over the YAG@AlN converter (2649 lm@31 W/ mm 2 ). These results highlight the potential of the YMA converter in high-brightness and efficiency laser-driven lighting.

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.

High-power laser-driven projection display demands that the phosphor converters possess excellent thermal handling capacity and stably efficient light output; however, simultaneously enhancing opto-thermal performance is still full of challenges. Herein, a novel universal architecture of phosphor-in-glass film (PiGF) on sapphire substrate with MgO-in-glass (MiG) layer coated on the other side is developed. Owing to the high refractive index of 1.74 and thermal conductivity of 50 W·m −1 ·K −1 of MgO, the MiG layer not only recycles the backscattering light but also improves the heat dissipation, leading to synergistically enhanced opto-thermal properties of PiGF. Taking Y 3 Al 5 O 12 : Ce 3+ (YAG) PiGF-sapphire-MiG (YSM) as a representative example, the optimized composite enables a high luminous flux (LF) of 5515 lm and luminous efficiency (LE) of 196.9 lm·W −1 at a luminescence saturation threshold (ST) of 28 W·mm −2 . After introducing red-emitting CaAlSiN 3 : Eu 2+ (CASN) component, the YAG-CASN PiGF-sapphire-MiG (YCSM) converter yields warm white light with a color rendering index (CRI) up to 90.6, enabling to realization of more details and more vivid color rendition of the laser projection system. This study provides a cost-effective, easy-prepared, and universal strategy for advancing high-efficiency PiGF-based color converters and high-power laser-driven applications.

A color converter is a critical component in realizing new-generation laser lighting because it displays thermal-induced luminescence saturation due to substantial heat accumulation. Herein, a multi-channel thermal design was introduced in a phosphor-in-glass film (PiGF) color converter, and a double-sided heat-conducting BN@PiGF@Al2O3 converter was proposed for high-brightness laser lighting. The BN@PiGF@Al2O3 was prepared via low-temperature sintering of a PiGF on a reflective Al2O3 substrate, which was then topped with a BN-in-glass (BiG) layer. The PiGF thickness was adjusted to control the photo-thermal performance of the laser-driven BN@PiGF@Al2O3. As the Y3Al5O12:Ce3+ (YAG) PiGF thickness reached 80 μm, the laser-driven BN@PiGF@Al2O3 emitted white light with a correlated color temperature (CCT) of 5823 K and a chromaticity coordinate of (0.3251, 0.3441) under a laser power density (LPD) of 30 W mm−2. The BN@PiGF@Al2O3 yielded a high luminous flux (LF) of 4784 lm@30 W mm−2, which was 1.39 times that of the traditional PiGF@Al2O3 converter with an LF of 3445 lm@18 W mm−2. Furthermore, the BN@PiGF@Al2O3 displayed a working temperature of 232 °C under an LPD of 30 W mm−2. The results demonstrate that the BN@PiGF@Al2O3 displays efficient double-sided heat transfer and improved luminescence saturation, making it a promising reflective color converter for high-brightness laser lighting.
