Abstract

Single crystal of heavily Yb³⁺-doped Lu₃Al ₅O₁₂ (Yb:LuAG) were grown by the micro-pulling-down method. Radio- and photoluminescence spectra of the Yb:LuAG were studied. Two bands peaking round 340-350 and 480-500 nm could be ascribed to charge transfer (CT) luminescence of Yb³⁺, as their position nearly coincide with the Yb³⁺-related CT emission in YAG matrix. The highest emission intensity was observed for Yb concentration of 5% with respect to the Lu site. Temperature dependence of photoluminescence spectra of the Yb: LuAG (5%) was measured and points to remarkable thermal quenching above liquid nitrogen temperature.
