● 论文摘要
CsPbX3 (X =Cl, Br, I) quantum dots (QDs) are considered to be candidate materials for applications in the field of photoelectric devices due to their remarkable photoelectric properties, such as high photoluminescence quantum yields (PLQYs), narrow emission wavelengths and easy synthesis. However, their instability and high toxicity restrict the further development of QDs. Here, we synthesized Sn-doped CsPb1−xSnxBr3 perovskite nanocrystals in borosilicate glasses (B2O3-SiO2-ZnO, BSZ) by traditional melt-quenching for the first time. The sample exhibited excellent air stability and thermal stability. Based on these results, white-light-emitting devices were fabricated by incorporating CsPb0.64Sn0.36Br3 QDs glasses and commercial red phosphor (CaAlSiN3:Eu2+) into a blue LED device. The tunable color coordinates of (0.3179-0.3596, 0.3174-0.3665) and adjustable correlated color temperature (CCT) from 6119K to 3128K were successfully achieved in the white light area, which could promote the application of metal ion-doped perovskite QDs in photoelectric devices.
