Abstract

Phosphate glasses with compositions (70-x) P2O5- 30ZnO- xCuO (where x= 10, 15 and 20 in mol%) have been prepared by melt-quenching Procedure. Effect of CuO percentage on the density of prepared samples has been studied. It was found that density decreases from 2.923 to 2.653 gm.cm-3 when CuO increases from 10 to 20 mol%. The values of molar volume (Vm), oxygen packing density (O. P. d), oxygen molar volume (VO), optical energy gap (Eopt) and glass transition temperature (Tg) of prepared glasses ware estimated. Moreover the UV-Vis-NIR spectroscopic study has been done and the optical properties of the prepared glasses were estimated. The optical band gap energy (Eopt) has been calculated, it was observed that Eopt increases from 3.33 eV to 3.43 eV with increasing CuO content from 10 to 20 mol%. Herein the glass system 60 P2O5- 30ZnO- 10CuO has two cut off wavelengths firstly at 420 nm and secondly at 1665 nm while the glasses modified by 15 and 20 mol% of CuO have only one cutoff wavelength in NIR region. The prepared glasses have transmission broad band from 1665 to 2940 nm. The structure of this glasses investigated by using Raman spectra. The optical properties results indicated that the prepared glasses are promising for optical filter applications in visible, NIR and IR region.
