Abstract

Thin films of Iron phthalocyanine have been deposited onto glass substrates by thermal evaporation technique at room temperature. The observed X-ray pattern suggests the presence of a crystalline phase of iron phthalocyanine in the asdeposited thin films. The electrical measurements (dc conductivity and photoconductivity) have been taken at different temperatures in the range 305-389 K. These films have been studied as chemical sensors such as methanol and ammonia. Electrical measurements indicate that these thin films have moderate sensitivity towards methanol and ammonia vapors..
