摘要	Bloch surface wave （BSW） is an electromagnetic mode in which the light field is localized in the surface layer and propagates along the surface layer of the photonic crystal. In this paper， a PS∶C545T organic luminescence layer was prepared on a one-dimensional photonic crystal， and the fluorescence of the exciton of organic C545T molecules coupled into the BSW mode was observed. By studying the performance of the output light emission of the sample through the hemispherical lens coupling， different characteristics of the conventional luminescence and the BSW mode luminescence of C545T are analyzed and compared. The results show that the coupled BSW mode outputs a ring light spot， which has the characteristics of narrow spatial distribution， linear polarization and adjustable spectral with angle， and is obviously separated from the light spot of the conventional radiation mode. The radiation transition rate of luminous films on one-dimensional photonic crystals is anisotropic， and the BSW mode fluorescence has a faster radiation transition rate. The above luminescence characteristics of BSW mode can be utilized to develop polarized light-emitting devices with certain directivity. © 2023 Chines Academy of Sciences. All rights reserved.
