Tm ³⁺ doped BaF₂ single crystal scintillator has been investigated. Undoped, 0.1, 0.5, and 1% Tm -doped BaF₂ are compared in terms of their decay time, light yield, non-proportionality and energy resolution. The fast component of Tm doped BaF₂is characterized by a 5 ̃ 6 ns decay time and it can be related to the Tm ³⁺ 5d-4fVUV emission from 4f ^n-15d low-spin state (parity allowed and spin allowed transition). The light yield of Tm doped BaF₂is lower with respect to the undoped BaF₂ and systematically decreases with increasing Tm concentration. However, 0.1%Tm:BaF₂showed a better non-proportionality and energy resolution than the undoped sample.
