Abstract

A new 1.75 μm infrared emission transition of Y 2O 3:Er 3+ is assigned to the 4S 3/24I 9/2 transition of Er 3+ ions situated at the C 2 sites of cubic RE 2O 3 (RE = Y, Gd, Lu). The intensities of features in the 1.54 μm 4I 15/2- 4I 13/2 absorption transition due to Er 3+ at S 6 and C 2 sites are consistent with the site occupation ratio and the relative magnetic dipole-electric dipole intensity contributions of Er 3+ at the different sites. The 1.54 μm emission lines are predominantly from Er 3+ ions at C 2 sites. The different behaviours of the emission intensities 1.75 and 1.54 μm groups with change in Er 3+ dopant ion concentration, preparation technique, Yb 3+ co-doping, temperature change and different excitation line are rationalized.
