Optical and EPR Spectroscopy of Er3+ Centers in KTaO3
Optical absorption, photoluminescence, and EPR of Er3+ impurity centers in KTaO3:Er single crystals was studied. This study proved the presence of at least two types of Er3+ impurity centers in KTaO3:Er crystals. T...

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 indicates...

Study of absorption spectra of Er3+ in KTaO3 crystals
The results obtained in the present study may be considered apparently 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 s...

Li-Lmpurity 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...

Optical absorption spectra and energy levels of Er3+ ions in KTaO3 crystals
The optical absorption spectra of erbium-doped potassium tantalate crystals have been studied. Absorption lines corresponding to the intraconfiguration f-f electron transitions from the 4I15/2 ground state to the levels 4F9/2,4S3/2,2H11/2,4F7/2,4F5/2...

Temperature shift of the zero-phonon f–f lines of Er3+ luminescence in quantum paraelectric KTaO3
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. Th...

An optical and dielectric spectroscopy study of Er3+-doped KTaO3.
the maininternal optical transitions in the 4f electronic shell of Er3+ in KTaO3. It was found are noncubic,formed by Er3+ substituting for K+ sites; these are responsible for the n-type......

Optical spectroscopy and unusual temperature shift of f - f zero-phonon luminescence lines: KTaO3:Er
We present a study of KTaO3:Er (~0.05%) single crystals based on a multifaceted soft mode of KTaO3. We provide information about energy level structures controlling f – f optical transitions in Er3+, on formation of minor c...
