The Photoluminescence and Physical Properties of Eu³⁺ Ions in Li₂O-Y₂O₃-B₂O₃ Glass System

Abstract:

The photoluminescence and physical properties of lithium yttrium borate glasses doped with Eu₂O₃ were studied in this work. The glasses were prepared by the melt-quenching technique and varied the Eu₂O₃ doped concentration between 0.00-1.50 mol%. We found that, the molar volume and density of these glasses showed linear increasing tendency with Eu₂O₃ concentration. The absorption bands were observed in UV and NIR region. For the Eu³⁺ doped glasses, the excitation bands centered at 363, 383, 394, 414, 465, 526 and 533 nm were observed with 613 nm emission wavelength. While in the emission spectra, the bands centered at 590, 613, 652 and 701 nm were observed with excitation of 394 nm. The intensity of excitation and emission bands increased with increasing of Eu₂O₃ concentration.
