Abstract
The optical spectra of the Yb-substituted Yb3Al5O12 (YAG) epitaxial films and the Yb ions recharging kinetics have been investigated by means of in-situ optical spectroscopy in the temperature range between 900 and 1100 °C at oxidation and reduction condition. This work continues the studies of the spectral properties of Yb:YAG epitaxial films represented in [1] and optical in-situ study of the re-oxidation kinetics of Yb3Al5O12 (YbAG) crystal represented in [2] where the model of internal oxidation of ytterbium ions Yb2+ → Yb3+ in the bulk crystal was developed and proofed. The changes of the absorption spectra of Yb:YAG film during oxidation and reduction were attributed to the recharging process Yb3+ ↔ Yb2+. It was found that the oxidation kinetics in epitaxial films do not agree to the model [2] and do not follow a parabolic rate law in contrary to bulk YbAG single crystal.
