Paper Abstract

In this paper, the optical properties induced by laser irradiation in managanese phthalocyanine [Mn(OH)Pc] thin film were investigated with the Ar+ laser (514.5 nm) irradiation. The reversible changes of spectra in the region of 630 - 750 nm were observed. The refractive index and extinction coefficient before and after laser irradiation were determined. The results imply 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).
