Abstract:

Lutetuim calcium silico borates (LuCaSiB) glasses doped with Nd3+ ions with molar composition of Lu2O3-CaO-SiO2-B2O3-Nd2O3 have been prepared by conventional melt quenching technique. Their properties have been evaluated throughout the density, refractive index, absorption and emission measurements. The density, molar volume and refractive index increase with increasing Nd2O3 concentration. The optical absorption spectra show twelve bands in visible and near infrared regions. The luminescence spectra exhibit three emission bands were observed at 900, 1072 and 1341 nm corresponding to 4F3/24I9/2, 4I11/2 and 4I13/2 transition respectively.
