Scintillation characteristics such as the pulse height, energy resolution, and decay time of single crystals of Tl-doped NaI (Tl:NaI), Ce-doped Lu<inf>2</inf>SiO<inf>5</inf>(Ce:LSO), Ce-doped YAlO<inf>3</inf>(Ce:YAP), Ce-doped Gd<inf>3</inf>(Al,Ga)<inf>5</inf>O<inf>12</inf>(Ce:GAGG), Pr-doped Lu<inf>3</inf>Al<inf>5</inf>O<inf>12</inf>(Pr:LuAG), undoped LuAG, and Ce-doped Y<inf>3</inf>Al<inf>5</inf>O<inf>12</inf>(Ce:YAG) transparent ceramics were compared at 25--150 °C to simulate well logging conditions. For increasing temperature, the light output of the scintillators decreased, mostly because of thermal quenching. Among these samples, Pr:LuAG demonstrated the highest scintillation performance at 150 °C.
