Abstract
Zinc oxide (ZnO) has attracted attention as an energy conversion material for optoelectronics and ionization radiation detector applications. ZnO thin films were fabricated on quartz substrates by using sol-gel and hydrothermal methods. The structural and the optical properties of ZnO thin films before and after gamma irradiation (0, 54.72, 109.44 and 164.16 kGy) have been systematically investigated. After irradiated with high dose gamma-ray: grain size has decreased; optical band-gap exhibited red-shift; radiation generated defect improved radiative recombination and affected Zn–O bond. The results indicated ZnO materials show high radiation hardness under high dose gamma-ray (60Co) radiation environment.
