Metal phthalocyanines are important among organic dyes because of their chemical and thermal stability. Thin film samples of tin phthalocyanine (SnPc) have been prepared for examination by thermal evaporation technique. Some optical and electrical properties of the samples were studied as a function of annealing temperature and Gamma radiation doses. Optical transition is found to be of direct type and optical band gaps are determined by analyzing the absorption spectrum. The activation energy of the dark conductivity is found to be highly dependent on both annealing and Gamma radiation doses.
