Abstract

The lithium sodium borate glasses doped with Eu3+ ion are prepared using melt quenching technique, their structural and optical properties have been evaluated. The density of prepared glasses exhibits an inverse behavior to the molar volume ranging from 2.26 g/cm3 to 2.43 g/cm3 and 26.95 cm3/mol to 26.20 cm3/mol, respectively. The absence of sharp peaks in XRD patterns confirms the amorphous nature of the prepared glasses. The absorption spectra yield four transitions centered at 391 nm (7F0→5L6), 463 nm (7F0→5D2), 531 nm (7F0→5D1), and 582 nm (7F0→5D0). The most intense red luminescence is observed at 612 nm corresponding to 5D0→7F2 transition under 390 nm laser excitations.
