Stable Zn-doped CsPbBr3 NCs glasses toward an enhanced optical performance for WLED
Source abstract
Abstract
Abstract Inorganic perovskite nanocrystals (NCs) doped with metal ions have received much attention due to their superior optoelectronic properties and environment friendly. Here, we synthesized Zn-doped CsPbBr3 perovskite NCs in borosilicate glass by melt-quenching. When ZnBr2 and PbBr2 were in half, the fluorescence intensity was enhanced, and the PLQYs increased from 32 to 36%. Under the excitation of 460 nm blue chip, white LED (WLED) was fabricated by using Zn-doped CsPbBr3 NCs glass and red phosphor powder CaAlSiN3:Eu2+. The experimental results show that the photoelectric parameters of the constructed white LED are considerable, among which the luminous efficacy (LE) is 70.1 lm/W, and a high LE is 72.79. However, pure CsPbBr3 has a low LE value of 26.1 lm/W and a CRI value of 76.9 Zn2+ doped CsPbBr3 can reduce the toxicity of materials and can be used to prepare high-performance optical devices. The study showed a new doped chemical model system for various optoelectronic applications.
