Abstract
Dye-doped polymer composite thin films were prepared by physical vapor deposition. The host matrix was polymerized by evaporating n-octadecylacrylate monomer using electron-assisted deposition polymerization method. The guest dye, tris-(8-hydroxyquinoline) aluminum, was introduced into the host matrix by simple coevaporation. The chemical composition can be easily adjusted by controlling the deposition rate of host and guest materials. Thermal stability of the composite films was studied by means of electron microscopy and surface plasmon resonance measurement. It was suggested that the glass transition temperature of the composite film varies with the composition, and the composite films have higher thermal stability compared to the monolithic film of guest dye.
