Abstract:Lead-free tin-based perovskite quantum dots (QDs) are considered the most promising alternatives to lead-based perovskites, but their potential application is hindered by poor stability. This issue was addressed by preparing amorphous glassprotected CsSnBr 3 QDs through meticulous optimization of the glass structure. Intriguingly, the self-crystallization of the CsSnBr 3 QDs occurred without needing heat treatment. We found that the CsSnBr 3 QDs glass-ceramic is composed of two phases, SnO 2 and CsSnBr 3 , of … Show more
