Abstract	We summarize the latest R&D; state-of-art of Ce 3+ and Pr 3+ -doped mixed (Lu x Y 1-x ) 3 Al 5 O 12 (LuYAG) garnet scintillator crystals and compare their properties with those of Lu 3 Al 5 O 12 (LuAG) and Y 3 Al 5 O 12 (YAG) single crystal analogues. Light yield, energy resolution and proportionality were studied under radioisotope excitation within 8-1300 keV energy range. The highest light yield of about 27000 ph/MeV is obtained in the newest prepared Ce 3+ -doped LuAG crystals while up to 17000 ph/MeV was measured in the Pr 3+ -doped ones. On the contrary, the energy resolution and proportionality are noticeably better in the Pr 3+ -doped crystals. Mixed Ce 3+ - or Pr 3+ -doped Lu x Y 1-x AG (x=0.9-1) crystals show comparable light yield and energy resolution compared to those doped pure LuAG, but the content of slow components in scintillation pulses lower.
