Abstract

A new 1.75 μm infrared emission transition of Y ₂O ₃:Er ³⁺ is assigned to the ⁴S _3/2 → ⁴I _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. © 2004 Elsevier B.V.
