Infrared and ESR spectroscopy of KTaO3:Er
Infrared reflection and ESR spectra of KTaO3:Er3+ single crystals have been investigated. The frequency of the lowest optical phonon mode TO1 has been found to increase as compared to undoped KTaO3 crystals, which ...

Study of absorption spectra of Er3+ in KTaO3 crystals
as the first observations of Er3+ f-f absorption spectra in KTaO3 crystals.The impurity erbium ions enter crystals usually in the form of Er3+ and can substitute in KTaO3 crystals theK+ or Ta5+ regular lattice ion...

Li-impurity effect in optical spectra of KTaO3:Er3+ crystals
The f-f absorption and emission spectra of Er3+ impurities were observed and identified in KTaO3 and K1 xLixTaO3 single crystals. It was shown that Li off-centers related random fields markedly influence intensity, width and positio...
