摘要：
A film of polyvinyl alcohol (PVA) and trypan blue dye is prepared via the casting method. The characterization of the film is carried out using the microscope and Image J software, x-ray diffraction (XRD), UV-vis spectrophotometer and computational chemistry using density functional theory (DFT). The prepared film optical properties are studied under the irradiation with gamma radiation of doses that varied in the range 14.4-57.6 Gy. The crystallite size of the film is studied using the Scherrer method and the Williamson-Hall method. Numbers of linear and nonlinear (NLO) parameters of the prepared film are obtained via the measurement of its absorbance and transmittance spectra before and after irradiation with the gamma radiation.
