Photoluminescence enhancement of CsPbBr3 quantum dots on Au island fiber film surface for optical communication and quantum information communication

Compared with the glass surface, photoluminescence intensity of CsPbBr3 quantum dots excited by 1200 nm femtosecond laser on surface Au island fiber film (AIF) is significantly enhanced. On other hand, decay AIF shows a fast average lifetime. The Photoluminescence enhancement effect was analysed spectrum, transmission electron microscope, absorption spectrum and decay. spectral changes are related to plasmon resonance. enhanced can be used in optical communication information communication.
