Two different variations between Na2O powders and cadmium oxide contained in phosphate glass with a series of 40P2O5-34ZnO-(21-x) Na2O- 5CuO- xCdO molar ratio with (x = 1,2,3… to 6 %) were prepared by conventional quenching melts technique. FTIR transmission spectra have been carried out. The most active peaks were observed in the region 400 cm–1 to 4000 cm–1. FT-IR spectra were analyzed to determine and differentiate the various vibrational modes by applying a deconvolution method to the FT- IR spectra. The values of vibrational modes of FTIR spectra were found to vary with the CdO content in glasses. It increase breaks the P-O-P bonds and non-oxygen bridges (NBOs) are created.
