Description
Summary:•CsPb2Br5 quantum dots (QDs) were successfully precipitated in borosilicate glasses.•HRTEM image confirmed that CsPb2Br5 were formed in the borosilicate glasses.•Photoluminescence spectra of CsPb2Br5 QDs were tuned from 500 to 519nm. Herein, CsPb2Br5 quantum dots (QDs) glasses have been successfully fabricated under various temperatures of heat-treatment. Moreover, photoluminescence (PL) spectra of CsPb2Br5 QDs were tuned from 500 to 519nm. Efficient green photoluminescence of CsPb2Br5 QDs glasses can be observed under ultraviolet or blue light exciation. This work offers great scientific insights to solve the instability of CsPb2Br5 QDs.
