This work aims to fabricate the Yb:LuScO 3 sesquioxides transparent ceramics for use in ultrafast and ultrashort laser technology. 1 at.% Yb:LuScO 3 nanopowders were fabricated using the glycine-nitrate process. ZrO(NO 3 ) 2 was selected as the precursor of ZrO 2 which functions as a sintering aid. Yb:LuScO 3 transparent ceramics with different ZrO 2 content were fabricated by vacuum sintering at 1780 °C and HIPing at 1650 °C, among which the ceramic with 7 at.% ZrO 2 showed the highest transmittance, reaching 81 % at 2000 nm. The ceramic achieved a maximum output power of 1.5 W at 1038 nm with a slope efficiency of 34.8 % and tunable wavelength range exceeding 22 nm. The results demonstrated that Yb:LuScO 3 transparent ceramics can be considered as promising materials in 1 μm solid-state laser applications.

For laser-driven white light sources, phosphor-in-glass films (PiGFs), typically sintered onto substrates with high-thermal conductivity, are developed and emerged as the leading materials. However, compared to other all-inorganic color converters, such as single crystals, transparent ceramics, PiGF suffers from a low saturation threshold, poor thermal stability and limited irradiation durability, which restricts its practical applications. To overcome these limitations, in this study, a series of h-BN-YAG:Ce 3+ PiGF is developed on opaque Al 2 O 3 /transparent Al 2 O 3 (B-Y PiGF@o/t-Al 2 O 3 ) by directly incorporating high-thermal-conductivity fillers into the PiGF. The selective incorporation of h-BN establishes a local heat conduction network, significantly increasing the saturation threshold and luminous flux. Through optimization, a maximum luminous flux of 6015.46 ± 14.46 lm with a saturation threshold of 16.15 ± 0.48 W mm −2 is achieved in reflective excitation mode, outperforming previous high-performance PiGFs. The addition of h-BN both enhanced heat dissipation and improved the uniformity of white light output in transmissive excitation mode, addressing the “yellow ring” effect commonly seen in laser-driven lighting. The application potential of the developed composite has been proven ranging from automotive headlights to medical lighting, offering a path toward enhanced brightness, more efficient, and operational-stable next-generation lighting technologies.

Fast neutron radiography offers exceptional penetration for high-density and bulky objects, yet its resolution is hindered by light scattering in conventional scintillators and screen fabrication techniques. To address this, here, we develop a transparent glassy Mn-based hybrid metal halide scintillation screen, (BTPP) 1.8 (HTPP) 0.2 MnBr 4 (BTPP + = butyltriphenylphosphonium, HTPP + = heptyltriphenylphosphonium), leveraging temperature-dependent ordered-disordered transitions. The large-area screen boasts >70% visible light transmittance (500–800 nm), a high photoluminescence quantum yield (~85.54%), and threefold higher light output than commercial ZnS (Ag): PP screens. With a spatial resolution of 5 lp mm −1 , it surpasses existing scintillators. This hybrid material enables imaging of heavy objects with clear hierarchical details, providing accurate data for non-destructive detection while offering an alternative approach to scintillator design, advancing the potential of fast neutron radiography.

Present DNA logic platforms mainly focused on distinguishing a specific kind of cancer cell from several other types of cell lines, while limited efforts have been paid to high-throughput recognition of cancer cells. A new DNA logic platform coupled with multivariate statistical analysis was developed to classify seven kinds of cancer cells. Four confined DNA circuits containing localized catalytic hairpin assembly (LCHA) and apurinic/apyrimidinic endonuclease 1 (APE1)-assisted circuits were conjugated to a protein of streptavidin (SA) for DNA logic platform. The mismatch minimizes the circuit leakage of the confined DNA circuits by inhibiting the incorrectly intramolecular structure switch. Benefitting from the spatial-confined effect, the DNA logic platform as a modified AND logic gate sensitively responded to the dual intracellular biomarkers, thereby generating strong dual fluorescent output signals in living cells. Based on the fluorescent cell imaging, multidimensional data collected from 50 individual cells were concatenated as a dataset for multivariate statistical analysis. Principal component analysis (PCA) shows distinct clustering among the seven kinds of cancer cell lines. A random forest algorithm obtained the specificity and sensitivity of 100%. Therefore, the DNA logic platform coupling with multivariate statistical analysis shows promising potential for cancer diagnosis and treatment.
