Effect of Pb2+ on the Luminescent Performance of Borosilicate Glass Coated CsPbBr3 Perovskite Quantum Dots
Source abstract
Abstract
Perovskite CsPbBr 3 quantum dots (PQDs) encapsulated within borosilicate glass can markedly improve their stability, expanding their applicability in sectors under lighting and display of light emitting diode (LED).However, this encapsulation has unintended consequence of reducing both the photoluminescence (PL) intensity and PL quantum yields (PLQY).This research aims to enhance the PL intensity of CsPbBr 3 perovskite quantum dots glass (PQDs@glass) by exploring the effects of thermal induction temperature and Pb 2+ content on its structural properties.The results demonstrate that the optimal thermal induction temperature for maximizing PL intensity is 460 ℃, with a Pb 2+ concentration of 6 mol.The study revealed that the increase in Pb 2+ concentration led to the densification of the 无
