Borate oxide glass system of composition: 30Y 2 O -43B 2 O 3 -7CuO -20ZnO where (Y= Li, Na and K) were prepared using the melt-quenching technique.Some physical properties were studied; such as X-ray diffraction, density, UV-Visible transmission spectra, ESR and FTIR.The density was measured by Archimedes method and the molar volume was calculated.It is found that density and the molar volume show...
