    • Abstract

       

      The optical transmission and absorption spectra in UV–VIS were recorded in the wavelength range 350–800 nm for different glass compositions in the system (CuO)𝑥(PbO)50–𝑥(Bi2O3)50 (𝑥 = 2.5, 5.0, 7.5, 10.0, 12.5, 15.0, 20.0). Absorption coefficient (𝛼), optical energy gap (𝐸opt), refractive index (𝑛D), optical dielectric constant ($\varepsilon_{\infty}^{′}$), measure of extent of band tailing (𝛥 𝐸), constant (𝛽) and ratio of carrier concentration to the effective mass (𝑁/𝑚*) have been reported. The effects of compositions of glasses on these parameters have been discussed. It has been indicated that a small compositional modification of the glasses lead to an important change in all the optical properties including non-linear behaviour. The optical parameters were found to be almost the same for different glasses in the same family.
