The optical properties of this glass system were studied with respect to the density, refractive index, optical energy gap, Urbach energy and polarizability. The oxide ion polarizabilities were deduced from two different experimental quantities viz., refractive index and optical band-gap energy. Results obtained are discussed in terms of the glass structure.]]>Dayanand, C., R.V.G. Sarma, G. Bhikshamaih and M. Salagram,1994167122126Dimitrov, V. and S.
