Development of gamma radiation dosimeter using copper phthalocyanine & zinc phthalocyanine based OFET

Abstract

Organic field effect transistor using copper phthalocyanine and zinc phthalocyanine as a source material are synthesized and investigated for Y-radiation dosimetry purposes. Samples are fabricated using thermal evaporation technique. The present investigation includes the studies on characteristics of both copper phthalocyanine and zinc phthalocyanine based organic transistor. The linear response to Y-radiation in the optical properties of copper phthalocyanine and zinc phthalocyanine were observed upto a certain level. The observed response suggest that copper phthalocyanine and zinc phthalocyanine based organic transistor can be considered as effective materials for room temperature Y-radiation dosimeters.
