Dye composite layers by physical vapor deposition

The embedding of dyes in metal halides, metal sulfides and metal oxides has become possible with the introduction of multi‐source physical vapor deposition (MSPVD). This in turn has led to potential applications such as colored layers, spectral sensitization of semiconductors and systems for controlled release of drugs. The technique of MSPVD is briefly described and the optical properties of the dye composite films are discussed.
