Abstract

The role of Al2O3 on the structural, physical and photoluminescence (PL) properties in x Al2O3 – (40-x) ZnO – 60 B2O3; (0≤x≤25) glass system have been investigated by means of FTIR and optical spectroscopic techniques. The samples were prepared by normal melt-quench technique. The absence of absorption band at 806 cm-1 is attributed to the progressive substitution of boroxol ring by triborate (BO3) and tetraborate (BO4) structural groups. The PL spectra exhibits four main emission bands, two lies in the blue-red and other two lies in blue-green region. The variation in density and molar volume of the present glass system are found to depend on Al2O3 content..
