دراسة تأثير التشعيع على الخواص البصرية لغشاء اوكسيد البزموث

Abstract

Thin films of Bi2 03 vere prepared by using ThcrntalEvaporation System on glass substrate. The films 'vereexposed to a low dose of (.,- rays. The optical properties of thirlt'rlms were studied before and atier irradiation ilr thefundarnental absorption region frorlr their absorption andtrarrsmission spectra. The energy gap of direct allorved andforbidden are measLlred also the absorption coefficient, theextinction coefficient, the index of refraction and dielectricconstant in its two parts and optical conductivity, werecalculated.
