The phosphate glass system of chemical composition 40P2O5 -37ZnO- 2CuO–(20 − x) Na2O–(x) V2O5in molar ratio with( x=1,2,3,4,5, and6). were prepared using a conventional melt-quench technique. The infrared spectra were measured over a continuous spectral range (400–4000 cm–1) in an attempt to study their structure systematically. The most active peaks were observed in the region from 400 cm–1 to 2500 cm–1. FT-IR spectra were analyzed to determine and differentiate the various vibrational modes by applying a deconvolution method to them. They show specific vibrations of phosphate units.
