Thermoluminescence properties of LSO:Ce and YSO:Ce films grown from PbO and Bi2O3 fluxes

Abstract

The comparative analysis of thermoluminescent properties of Ce-doped single crystalline films (SCF) of Lu₂SiO₅ (LSO) and Y₂SiO₅ (YSO) orthosilicates, grown by LPE method from two different (PbO and Bi₂O₃) fluxes were performed in this work. We show that the difference in technology of material preparation resulted in different thermoluminescent behaviors of LSO:Ce and YSO:Ce SCFs caused by the formation of the Pb²⁺-Ce⁴⁺ and Bi³⁺-Ce³⁺ centers in them.
