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