Abstract:Perovskite quantum dots (PQDs) have shown great promise in optoelectronic device applications. Typically, a traditional hot-injection method with heating and high vacuum pressure is used to synthesize these colloidal nanoparticles. In this article, we report a low-cost synthetic method for FAPbI3 PQDs in air at atmospheric pressure with the assistance of ZnI2. Compared with the FAPbI3 PQDs synthesized under vacuum/N2 condition, the air-synthesized Zn:FAPbI3 PQDs exhibit the same crystalline structure with a si… 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.
