Temperature shift of the zero-phonon f–f lines of Er3+ luminescence in quantum paraelectric KTaO3
Original language description
In KTaO3:Er crystals, we observed a temperature shift, unusual for rare earth impurities, for narrow zero-phonon luminescence lines, due to the 4S3/2 → 4I13/2, 4F9/2 → 4I15/2, and 4S3/2 → 4I15/2 transitions in Er3+ impurity ions. The magnitude of the shifts turned out to be comparable with the large shifts of the R lines of the Cr3+ luminescence in SrTiO3:Cr and KTaO3 :Cr crystals, that is, substantially larger than that for the three-charged rare earth ions usually observed in the f–f luminescence spectra in ionic crystals.
