تحضير غشاء لأوكسيد النحاس ودراسة تأثير التشعيع على الخواص البصرية

Abstract

Thin films of Cu2O were prepared by using ThcrmalEvaporation System on glass substrate. The films wereexposed 10 a low dose ofl - rays. The optical properties of thinfilms were studied before and after irradiation in tliefundamental absorption region tiom their absorption andtransmission spectra. The energy gap of direct allowed aremeasured also the absorption coefficient, the cxtinctioncoefficient, the index of refraclion and dielectric constant in itstwo parts and optical conductivity, were calculated.
