Temperature dependent scintillation properties and mechanisms of (PEA)PbBr single crystals.

In this work the scintillation properties of PEAPbBr are studied as function of temperature, accessing the potential use of these materials for low temperature applications. The scintillation properties and mechanism have been studied using a combination of temperature dependent photoluminescence emission and excitation, X-ray excited emission and decay measurements. At room temperature the X-ray excited emission is dominated by the 442 nm emission with a lifetime of 35.
