Photoluminescence of plasma polymerized methyl methacrylate films

The photoluminescence properties of plasma polymerized methyl methacrylate films are investigated. The photoluminescence is a fluorescence rather than a phosphorescence process with a lifetime on the order of a few nanoseconds. The photoluminescence is a one-photon volume effect. The wavelength span of the photoluminescence using suitable UV excitation can reach over 300 nm with a FWHM exceeding 200 nm. These photoluminescent films may find potential applications in wavelength transformers for solar cells or as a gain medium for tunable solid-state dye lasers.
