“In the field of high-energy X-ray imaging, (Gd, Lu)2O3:Eu scintillation ceramics have shown promising applications. Researchers have prepared Eu0.1Gd0.6Lu1.3O3 nano-powders with pure phase and investigated the influence of pre-sintering temperature on the microstructure, optical and luminescence properties. The Eu0.1Gd0.6Lu1.3O3 ceramics pre-sintered at 1 625 ℃ for 2 h combined with HIP post-treatment show the highest in-line transmittance of 75.2% at 611 nm. The PL, PLE and XEL intensities of the HIP post-treated Eu0.1Gd0.6Lu1.3O3 ceramics show a trend of first ascending and then descending with the increase of pre-sintering temperature.”
“In the field of 2D transition metal dichalcogenides, researchers have reported a photoluminescence enhancement effect of 1L WS2 at room temperature when constructing it into 1L-WS2/hBN/1L-MoS2 vertical heterostructures. The photoluminescence enhancement factors can be up to 4.2, which provides a feasible way to optimize the performance of TMD-based optoelectronic devices.”
