Abstract： The non-radiative energy transfer between the organic dye donor and acceptor coupled into the cavity has been proven to be extremely efective when forming a light-matter mixed state. In this study，a physically separated composite organic dye film structure was used to construct a Fabry-Perot （F-P） cavity for the formation of a light-mater mixed state，and this structure was fabricated on a single quartz wafer. This structure exhibited excellnt tolerance to variations in dye concentration and film thickness. By adjusting the cavity length， the exciton resonance frequency could be accurately matched， resulting in obvious Rabi splitting， which significantly changed the absorption and emission characteristics of the dye in the cavity. At the same time， the structure showed relative stability on the time scale.After the storage for1 month and 3 months，there was no obvious change in its absorption spectrum and emission spectrum. The construction of this structure opens up new possbilities for the development of thin-film devices for energy conversion， expands the design concepts of such devices，and holds great significance for the study of energy collection and transmission processes.
