Abstract

In order to investigate proper hosts for charge transitions (CT) of Yb3+, the gallium garnet host (YGG) and aluminium garnet host (LuAG) were studied. Transparent and crack-free heavily Yb-doped YGG, i.e. {Y3-x,Ybx}[Ga]2(Ga)3O12, x = 0.15, 0.5, 1.0 and heavily Yb-doped LuAG, i.e. {Lu2Yb1}[Al]2(Al)3O12 single crystals were grown by the modified pulling-down method with 〈111〉 orientation. Emission, excitation spectra and decay kinetics were measured for these crystals. The CT of Yb3+ in the YGG host were discussed compared with the Yb3+ one in the LuAG host.
