Paper Abstract

With the purpose of investigation on the visible emission properties of Tm3+ ions, a Tm3+-doped Y2O3 transparent ceramic was fabricated by sintering at 1800 °C for 20 hour with a vacuum degree of 1x10-3 Pa. 3 at% ZrO2 was introduced as the sintering aid and the average grain size was measured to be 22 μm. The optical transmittance of the ceramic achieved 76.3 % at 1 μm. The PL spectra at room temperature and low temperature were measured under 361 nm excitation. The ~453 nm emission bands were observed and the luminescence mechanisms were discussed. It was found that the Tm: Y2O3 transparent ceramic have the potential to be used in white LED packaging structure.
