SENSITIVE X-RAY AND GAMMA-RAY DETECTORS INCLUDING PEROVSKITE SINGLE CRYSTALS

摘要

Perovskite single crystal X-ray and gamma-ray radiation detector devices include an X-ray and gamma-ray wavelength responsive active layer including a perovskite single crystal. The perovskite single crystal is a perovskite single crystal having a structure of ABX₃, wherein A is methylammonium (CH₃NH₃+), C_s+, formamidinum (H₂NCHNH₂+), or Rb+ or a mixture thereof, B is Pb²⁺ which can be partially or completely replaced by other ions including Bi³⁺, Sb³⁺, Sn²⁺ or a mixture thereof, and X is a halide anion, thiocyanate (SCN−) or a mixture thereof
