Sm3+-doped CsPbBr3 NCs glass: A luminescent material for potential use in lighting engineering
Source abstract
Abstract
Abstract Since being synthesized, CsPbX3 (X = Cl, Br or I) quantum dots (QDs) have gained increased interest due to their superior performances in photovoltaic applications. Herein, Sm3+-doped CsPbBr3 nanocrystallines (NCs) were successfully prepared in zinc borosilicate sodium (ZnO–B2O3–SiO2–Na2CO3, ZBSN) glass, and the as-prepared glass exhibited a strong red emission, which was attributed to the effects of the energy level transitions in Sm3+. Importantly, white light-emitting diodes (W-LEDs) were prepared by combining the glass with a blue InGaN chip, eliminating the need for a red phosphor to provide the red light, and white light was generated with a high colour rendering index (CRI: 82.6), a low correlated colour temperature (CCT: 4455 K) and colour coordinates in the white light region (0.3547, 0.3234). The glasses show excellent stability at 85 °C and 85% RH. Therefore, the Sm3+-doped CsPbBr3 NCs glass can be used as a colour converter for application in lighting engineering.
