Opis

The book deals with the studies on "Microstructural, dielectric and spectroscopic properties of Li2O-Nb2O5-ZrO2-SiO2 glass system crystallized with CuO and V2O5 & Emission features of Nd3+ and Ho3+ ions in Li2O-Nb2O5/Ta2O5/La2O3-ZrO2-SiO2 glass systems". This work has been carried out in the Department of Physics, Acharya Nagarjuna University - Dr.M.R.A.R Campus, Nuzvid. The book contains the methods of preparation,characterization and studies on dielectric and spectroscopic properties including photo-induced second order susceptibility studies of Li2O-Nb2O5-ZrO2-SiO2 glass systems crystallized with varying concentration of CuO and V2O5 and also the spectroscopic properties Li2O-Nb2O5/Ta2O5/La2O3-ZrO2-SiO2 glasses doped with Nd3+ and Ho3+ ions.SiO2 serves as the prototype of a glass. Its structure is the simplest of all glass structures. The structural unit consists of slightly distorted SiO4 tetrahedra with all BOs. Hence a strongly connected three-dimensional network is established. The disorder in the structure is caused mainly by variations in the bond angles  and the torsion angles and only to a minor extend by the distortion of the tetrahedra.
