A Cyan Emitting CsPbBr 3 Perovskite Quantum Dot Glass with Bi Doping
Source abstract
Abstract
CsPbBr 3 :xBi 3+ quantum dot glass was prepared by using traditional melting-quenching and heat treatment processes. The effects of Bi doing on the sinter of the precursor of glass and the crystalline of the perovskite quantum dot were discussed detailly. By doping Bi 2 O 3 into the borosilicate glass matrix, the melting temperature was reduced to 900 °C. The tunable emission of CsPbBr 3 quantum dots from 523 to 493 nm was achieved with suitable Bi 2 O 3 doping. Due to the protection of the inorganic glass matrix, the prepared CsPbBr 3 quantum dots still exhibit excellent thermal stability after multiple thermal cycles and thermal shocks. This provides a good solution to the problem of poor thermal stability of perovskite quantum dots.
