Abstract

Here we report X- and gamma-ray scintillation properties from solution-processable perovskite (SPP) halide single crystals and quantum dots. We tune the properties of single crystals by replacing the cation, changing the organic ammonium cation spacer, and varying the halide anion. For quantum dots, we tune the properties by changing the halide ion composition while we also try to replace the lead with the bismuth. Finally, we summarize the advantages and disadvantages of SPP single crystals and quantum dots to pave the way the research for the new high light yield scintillators.
