摘要

A transparent and emitting ceramic of Y2O3 doped with 6％ Tm3+ ions is fabricated by vacuum sintering with ZrO2.Absorption,photoluminescence (PL),and PL excitation (PLE) spectra are investigated in a spectral range of 200 to 2 100 nm at various temperatures between 296 and 12 K.Intense emission band appears at 450 to 465 nm in the visible range.Near-infrared emission bands are observed at 1 200 to 1 300nm and 1 400 to 1 550 nm,with intense peaks at 1 270,1 450,and 1 523 nm.The luminescence mechanisms and potential applications of the emissions are discussed with the help of Judd-Ofelt theory and PLE spectra.
