摘要：
The work devoted to the investigation of a new luminescent and scintillation material based on the single crystalline films (SCFs) of Tm3-x,Lu(x)AG:Ce garnet; x = 0-1.5, grown by LPE method from PbO based flux. The best scintillation properties are achieved for SCFs of Tm1.5Lu1.5Al5O12:Ce composition. We have found that direct Tm -> Ce and backside Ce -> Tm energy transfer processes are observed in Tm1.5Lu1.5Al5O12:Ce. Due to elimination of traps in the 300-450 degrees C range, the relatively fast scintillation decay is realized in highly doped Tm1.5Lu1.5Al5O12:Ce SCFs. For this reason, Tm doping can be considered as a suitable way for improvement of the scintillation efficiency in other Ce3+ doped garnet compounds. (C) 2016 Elsevier B.V. All rights reserved.
