Abstract
- Luminescence properties of heavily Yb-doped <f>Lu3Al5O12</f> (Yb:LuAG) and <f>Lu3Ga5O12</f> (Yb:LGG) single crystals grown by micro-pulling-down method were characterized. Charge transfer luminescence of <f>Yb3+</f> was observed in both crystals. Photoluminescence spectra, temperature dependence of emission intensity and decay kinetics of these crystals were studied. Mean decay time of about <f>24 ns</f> at <f>90 K</f> (Yb5%:LuAG) and <f>21 ns</f> at <f>110 K</f> (Yb5%:LuGG) were observed. Strong thermal quenching at room temperature was measured for both Yb:LuAG and Yb:LGG. [Copyright &y& Elsevier]
