Alkali oxy borate glasses are well known due to their variety of applications in phosphors, solar energy converters and in a number of electronic devices. Transition metal ions are very interesting ions to probe in the glass network because they exist in different valence states and influence the physical properties of the glasses to a substantial extent. Different concentrations of Cu2+ doped (0.1, 0.2, 0.3, 0.4, 0.5 and 0.6mol%) Li2O-ZnO-B2O3 glasseswere prepared using melting and quenching technique. The prepared material was characterized by optical absorption spectra and physical, dielectric properties were measured. From optical absorption spectra the prepared sample was tetragonally distorted octahedral symmetry.
