Abstract

Capacitive devices with Ag/CuPc/Ag sandwich structure were fabricated using screen-printing. The effects of γ-radiation on their optical and electrical properties were investigated for the purpose of dosimetry applications. The energy values of the optical band gap showed irregular slight increase when the CuPc thick films were irradiated. The as-printed (unexposed to γ-rays) and irradiated Ag/CuPc/Ag devices demonstrated a Schottky conduction mechanism. The absorbance and the capacitance of the CuPc thick films exhibited highly consistent linear response to the exposure of γ-radiation
