Optical Recording Properties of Copper Phthalocyanine Film
Optical absorption spectra and optical constants of the vacuum sublimed films of copper phthalocyanine (CuPc) were studied. A comparatively strong absorption was oberved at wavelength region of 550 to 750 nm. The static optical recording test of a CuPc film indicated that low power He-Ne laser irradiation could produce a relatively large reflectivity change. The introduction of metallic reflective layer on the recording layer will raise the writing threshold energies and maximize the reflectivity contrast.
