Vanadyl phthalocyanine: An organic material for optical data recording

Vanadyl Phthalocyanine (VOPc) is a stable organic dye which absorbs in the spectral range of currently available injection lasers. The applicability for high density optical storage of single, double and triple layer structures containing a thin film of this dye, is investigated. It is concluded that if VOPc is used in combination with a tellurium film, some power reduction relative to single Te films can be achieved.
