Abstract:Lanthanide ions (Ln3+) doped near‐infrared (NIR) phosphors play a critical role in applications requiring a compact, reliable, and economical NIR light source, but as yet they suffer from weak and narrow‐band absorption because of intrinsic photophysical limitations of Ln3+. Here, CsPbBr3 perovskite quantum dots (PQDs) and Nd3+ co‐doped tellurite glassy phosphor is designed to significantly upgrade the NIR photoluminescence (PL) efficiency of Ln3+. Benefiting from the sensitization effect of the PQDs on Nd3+, … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
