Spontaneous emission lifetimes of fluorescent dye layers in front of a metallic mirror were observed using a picosecond time-resolved fluorescence measurement system. Multilayer thin-film samples composed of glass substrate/indium-tinoxide layer/organic spacer layer/emission dye layer/organic spacer layer/MgAg mirror were prepared with vacuum-vapor deposition. The distance between an MgAg mirror and an emission dye layer was varied from 25 to 180 nm. The emission lifetime of the fluorescent dye layer largely depended on the MgAg mirror-emission layer distance and assumed a maximum at around 150 nm. A promising application of organic multilayer structures for the study on optical microcavity was suggested.
