A Study of Infrared Spectra of Some Semiconducting Oxide Glasses

Glass samples in the systems of (p2o5)75-(cuo)25-x- (cdo)x,(p2o5)75-(cuo)25-x-(zno)x, (p2o5)75-(cuo)25-x-(v2o5)x, (p2o5)50-(teo2)50-x-(zno)x, (p2o5)50-(teo2)50-x-(cdo)x and (p2o5)50(teo2)50-x-(v2o5) x of different compositions where(x=0,5,10,15, 20)were prepared by the melt-quenching technique. density measurements of (p2o5)75-(cuo)25-x-(cdo)x,(p2o5)75-(cuo)25-x–(zno)x and (p2o5)50-(teo2)50-x-(cdo)x show decreasing in density with the increasing of cdo and zno contents. the density of (p2o5)75-(cuo)25-x-(v2o5)x,(p2o5)50-(teo2)50-x-(zno)x and (p2o5)50- (teo2)50-x-(v2o5)x glasses show increasing in density with the increasing of v2o5 and zno contents in the glass.the infra-red spectra were recorded for (p2o5)75-(cuo)25-x- (cdo)x,(p2o5)75-(cuo)25-x–(zno)x and (p2o5)75-cuo)25-x-(v2o5)x the band positions of such glasses show that (475.27-503.15) cm-1can be attributed to (po4)-3,the infra-red spectra of (p2o5)50-(teo2)50-x-(cdo)x,(p2o5)50-(teo2)50-x-(zno)xand(p2o5)50-(teo2)50-x- (v2o5)x were recorded in the range(4000-400) cm-1.the band positions of such glasses shown that(494.83-498.77)cm-1can be attributed to te-o-te linkages
