Abstract

Thin films of tetra-neopentoxy phthalocyanine zinc (TNPPcZn) were prepared from its toluene solution by spin-coating technique. Their structural changes due to heat treatment were characterized by the change in optical absorption. The static rewritable optical storage performance of these thin films with recording wavelength at 632.8 nm was investigated. Under the selected writing and erasing conditions, 35 cycles was realized in the static measurement. The reflectivity contrast was in the range of -20% to approximately 20%.
