Abstract

The photoluminescence properties of lithium yttrium borate glasses doped with Eu3+ (LiYB:Eu3+) were studied in this work. Glass samples were prepared by melt-quenching technique with variation of Eu2O3 doped concentration between 0.00-6.00 mol%. The absorption spectra show that LiYB:Eu3+ glasses absorbed photon in visible light (VIS) and near-infrared (NIR) region. Photon absorption at 394 nm can excite glass to emit the number of photons in VIS region such as 591, 613, 653 and 701 nm. The strongest emission belong to the light with 613 nm wavelength. The optimum concentration of Eu2O3 for LiYB glass is 4.00 mol%. Judd-Oflet (J-O) analysis was used to study on 4.00 mol% doped glass, which shows the interesting potential for using this glass as gain medium in 701 nm emitting laser.
