WebPhotoluminescence (PL) property data for reported α-Si 3 N 4 to date are scattered and it is difficult to clarify the reason only through experimental study. In this paper, the relationship between photoluminescence and intrinsic point defects in α-Si 3 N 4 has been established accordingly via band structure modelling based on density functional theory … WebAug 27, 2014 · We report on the second family of layered perovskite white-light emitters with improved photoluminescence quantum efficiencies (PLQEs). Upon near-ultraviolet excitation, two new Pb–Cl and Pb–Br perovskites emit broadband “cold” and “warm” white light, respectively, with high color rendition. Emission from large, single crystals indicates …

WebIntrinsic white-light photoluminescent rare-earth free materials are promising candidates in the field of environment-friendly optical devices. They are important because white … WebPhotoluminescence (PL) spectroscopy has been the workhorse of the optical characterization techniques due to its non-destructive nature and ability to yield valuable … WebJul 24, 2024 · Here we report methods for fabricating high quality TMDC monolayers with narrow photoluminescence (PL) linewidth approaching the intrinsic limit. We find that encapsulation in hexagonal boron nitride (h-BN) sharply reduces the PL linewidth, and that passivation of the oxide substrate by an alkyl monolayer further decreases the linewidth … intresting math cba ideas
