Abstract: Copper doped sodium leadbismuthate glasses were prepared in the chemical composition (wt.%) 35Bi2O3 + 35PbO + (30 − x)Na2O + xCuO (where x = 1, 2, 3 and 4). The optical spectra of the glasses have been investigated. The optical absorption spectra of Cu2+ doped glasses show a broad absorption band between 560 and 880 nm, which is attributed to the 2Eg → 2T2g transition of Cu2+ ion. FTIR spectral studies confirm the Bi–O bonds and the presence of [BiO3] pyramidal units.
