The Li+ co-doped Ce:Lu3Al5O12 single crystals were prepared by micro pulling down method. Absorption and luminescence spectra were measured together with several other scintillation characteristics, namely the scintillation decay and light yield to reveal the effect of the co-doping. The smooth Ce4+ CT absorption below 350 nm is clearly enhanced with increasing concentration of Li. The scintillation decays were accelerated and light yields were increased by Li co-doping.
