Abstract
Abstract The effect of heat treatment on the optical band gap and refractive index dispersion of 2,9,16,23-tetraneopentoxyphthalocyaninato zinc(II) thin film has been investigated. The absorption edge with increasing annealing temperature was shifted to the lower energy side and fundamental absorption edge is formed by a direct allowed transition. The refractive index and dispersion parameters E o and E d of the thin film were determined. The obtained results show that the film is suitable to change refractive index and oscillator parameters by heat treatment.
