Erasable Cs4PbBr6 quantum dots glass with switchable photoluminescence
Encapsulating quantum dots (QDs) into a transparent glass matrix can not only increase their stability but also explore new luminescence properties. Herein, erasable Cs4PbBr6 QDs with switchable photoluminescence are successfully obtained by a heat-treatment method in a borosilicate glass matrix. First, QDs can self-crystalize in borosilicate glass without the heat treatment. Second, it is found that when the QDs glass is heat treated below Tg, QDs can be destroyed. Further, when the QDs glass is reheat treated above Tg, atom rearrangement can occur and QDs can reprecipitate in the glass matrix. Consequently, the switchable photoluminescence of QDs can be achieved. The special erasable QDs glass and switchable photoluminescence in this work can resolve the technological challenge of recovering the luminescence performance of QDs after they have been destroyed.
