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: BO: 25%-45%, SiO: 25%-45%, MCO: 1%-10%, AlO: 1%-10%, ZnO: 1%-5%, CsCO: 1%-10%, PbCl: 1%-10%, NaCl: 1%-10%, MnCl: 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.
