摘要	One-dimensional photonic crystals （1DPCs） are artificially constructed periodic optical dielectric structures. 1DPCs can modulate the luminescent material mainly by defect mode modulation and band-edge mode modulation. 1DPC band-edge mode with a large density of photonic states can effectively modulate the luminescent properties of the luminescent material. In this paper， the fluorescence emission of colloidal quantum dot （CQD） materials coated on the surface of 1DPC is studied. By using different QD materials， different surface film thicknesses， and different angles for fluorescence detection， luminescence characteristics of the samples have been investigated. The results show that 1DPC band edge mode can effectively regulate the luminescence characteristics of CQD films located in the surface layer， effectively enhance the fluorescence emission intensity and narrow the emission linewidth. CQD materials controlled by 1DPC band edge mode have faster fluorescence radiation transition rate. The influence of 1DPC on the luminescent properties of CQD materials is helpful to optimize the design of the device structure， so as to greatly improve the performance of the luminescent devices. © 2023 Chines Academy of Sciences.
