| Abstract |
Lead halide nanocrystals (NCs) perovskites CsPbBr3 and FA-doped CsPbBr3 (FA=Formamidinium)(CH(NH2)2) are synthesized at room temperature without the protection of inert gas for low-cost optoelectronics and photonics. The free amino groups are employed as surface ligands for growing perovskites NCs with a size of ~ 22nm. The PL emission peaks of pure and FA-doped CsPbBr3 NCs shift from 514 to 518nm with increase amount of doped FA ion and the bandwidth of peaks is narrow (full width at half maximum (FWHM) of 26~28 nm). In addition, we demonstrate the electrical and electroluminescence performance of solution-processed light-emitting diodes (LEDs) based on our perovskites NCs. These results demonstrate that the as-obtained colloidal perovskites NCs are promising solution-processed emitter for LED in the future applications. |
