文摘

In this paper, we report pure and 5 mol% Nd doped Ca₃La₂ (BO₃)₄ glasses and their spectroscopic properties. A ternary system La₂O-3CaO-4H₃BO₃ was adopted and glasses were prepared by using a conventional melt quenching technique. The amorphous nature of the glasses has been confirmed by powder X-ray diffraction analysis. In order to study the spectroscopic properties of fabricated glasses, ultraviolet-visible transmission and absorption spectroscopy has been performed. The absorption spectrum of Nd doped glass shows that the transition ⁴I_9/2→⁴G_5/2+²G_7/2 is more intense as compared to the other transitions. Optical band gap energies of both glasses have been determined and found decreased for Nd doped glass as compare to pure glass.
