Cs2HfCl6 doped with Zr: Influence of tetravalent substitution on scintillation properties

Popis výsledku v původním jazyce

Detection and identification of radioactive materials in cargo transport requires scintillators with excellent energy resolution and high light output. State-of-the-art halide scintillators e.g. SrI2:Eu or LaBr3:Ce can satisfy the requirements for light yield and energy resolution, but the production costs are very high due to complicated crystal growth and the high prices of rare earth metals. Cesium hafnium chloride (Cs2HfCl6) is a promising intrinsic scintillator with high light yield and excellent resolution. Moreover, its low hygroscopicity and cubic crystal structure could allow lower production costs compared to SrI2 or LaBr3. Luminescence of Cs2HfCl6 is commonly attributed to STEs. However, the luminescence of Cs2HfCl6 shows complex structure and temperature dependence. This might be explained by the presence of zirconium which is a common impurity in hafnium compounds.
