Correlation of emission, scintillation and charge trapping properties in Cs2HfCl6 and Cs2ZrCl6 single crystals
Original language description
The temperature dependence of the scintillation light output exhibits an unusual s-shaped character with the drop at around 100 K that correlates well with the decrease in the Vk(a) EPR signal, evidencing detrapping of holes trapped at the Vk(a) center in the Cs2(a)HfCl6 (CHC) crystal. Therefore, the Vk(a) center was assumed to be the part of Hf3+–Cl2- self-trapped exciton (STE) that participates in the emission above 100 K becoming ‘‘frozen’’ below 100 K. RL and TSL spectra were complex in the CHC sample composed of two and three overlapping bands, respectively. One of the components peaking at 2.65 eV originated from the Zr-related STE.
