Divalent manganese-doped all-inorganic perovskite quantum dot glass and preparation method thereof

Abstract

The present invention relates to a divalent manganese-doped all-inorganic perovskite quantum dot glass, and constituents of the divalent manganese-doped all-inorganic perovskite quantum dot glass are as follows: B2O3: 25%-45%, SiO2: 25%-45%, MCO3: 1%-10%, Al2O3: 1%-10%, ZnO: 1%-5%, Cs2CO3: 1%-10%, PbCl2: 1%-10%, NaCl: 1%-10%, MnCl2: 1%-10%, wherein M is Ca, Sr or Ba. Preparation of the quantum dot glass is as follows: grinding each raw constituent materials and mixing well to form a mixture, melting the mixture, followed by molding, annealing and performing thermal treatment. By the thermal treatment at different temperatures, a divalent manganese-doped quantum dot glass can be obtained. The divalent manganese ions doped perovskite quantum dot glass is a kind of light-emitting material with great application prospect, for possessing good stability and rather high fluorescence quantum yield.
