摘要: Abstract The effect of 100 MeV Ag +7 ion irradiation on the properties thermally evaporated CdS thin films has been investigated. structure studied is polycrystalline with a mixture dominant hexagonal and few traces cubic phases. A shift in peak position due to was observed discussed basis change residual stress. Annihilation microcracks induced grain growth from SEM micrographs at lower fluences. optical transmittance absorption spectra revealed fundamental edge hence variations band gap. gap energy estimated for as-deposited irradiated found decreases upon irradiation. significant increase refractive index after
