| 摘 要： | 采用室温合成法制备出一系列具有高发光效率和多色发光的CsPbX3钙钛矿量子点(PQDs),反应全过程快速简便,且通过调节不同的卤素组成(Cl,Br,I)可以实现CsPbX3 PQD的多色发光。 通过表征证明,CsPbX3 PQDs呈立方晶型,平均粒径约为10 nm,发射光谱覆盖可见光波长范围为410~630 nm,半峰宽14~38 nm,荧光量子产率10%~90%。 最后将CsPbX3 PQDs应用于发光二极管(LED)器件的制备中,在恒定电压下工作时,能保持LED器件的发光颜色、强度和颜色坐标不变。

| Abstract: | Highly efficient and polychromatic luminescent CsPbX3 perovskite quantum dots(PQDs) were synthesized under room temperature. The entire reaction is very fast and simple. Polychromatic luminescence of CsPbX3 PQDs can be achieved by adjusting different halide compositions(Cl, Br, I). The as-prepared CsPbX3 PQDs have a cubic morphology with an average size about 10 nm. The photoluminescence of CsPbX3 PQDs has a characteristic of wide visible spectral region of 410~630 nm, narrow emission line-widths of 14~38 nm and quantum yields of 10%~90%. Finally, the CsPbX3 PQDs are successfully applied to prepare light emitting diode(LED) devices. At a constant voltage work for a long time, the emission color, intensity, and color coordinates of the LED device remain unchanged. |
