Synthesis and Fabrication of Luminescence of CsPbBr3/PAN Nanocomposite Fiber

Abstract:

Perovskite semiconductor have gained increasing attention in the recent years. However, pristine halide perovskites often faces bottle-neck related to low their stability. Herein, for the first time synthesis and fabrication of CsPbBr3/PAN fiber composite with electrospinning method is reported. CsPbBr3 quantum dots (QDs) embedded PAN fiber were successfully fabricated based on the XRD and FTIR test result. The result demonstrates electrospun fiber stable for over than one week in the condition of being immersed in water. The CsPbBr3 QDs was synthesized by Ligand Assisted Reprecipitation Process (LARP) method. The average particle size of our CsPbBr3 particle sizes ranging from 80 to 240 nm. Our findings reveal that the effect of variations between toluene and acetone had an effect on the size of the fiber and the intensity of photoluminescence reduction of the CsPbBr3/PAN fiber composite. Which is the smallest fiber and the lowest reduction intensity belongs to the 4:1 variation, namely with a fiber size of a 727.56 nm and a percentage decrease in intensity of 66,67%.
