Paper Abstract

Optical and morphological properties induced by laser irradiation in oxotitanium phthalocyanine (TiOPc) film were investigated at 650 nm wavelength with semiconductor laser. The reversible changes of spectra in the region of 610 - 730 nm wavelength were observed. The varieties of refractive index and extinction coefficient of the film before and after laser irradiation were detected. The morphological structure was investigated with transmission electron microscope (TEM) as well. The results suggest that the changes of the film optical properties are induced by photo-thermal processes, and this characteristic is significant to phthalocyanine film as promising candidate for DVD-rewritable recording medium (DVD-RW).
