Abstract:In our study, we investigated the crystal structure and optical properties of multiphase CsPbBr 3 quantum dots (QDs). CsPbBr 3 QDs can exist in three different crystal structures, but distinguishing them using X-ray diffraction (XRD) is challenging due to their high similarity. Therefore, we utilized XRD and Lasso-regression analysis to successfully differentiate between the cubic and orthorhombic phases of CsPbBr 3 QDs. Additionally, we examined the photoluminescence properties of the QDs, including their emi… 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.
