1. An X-ray detection system, comprising:
a nanocrystal scintillation material for absorbing X-rays and emitting visible photons, wherein the nanocrystal scintillation material comprises a plurality of halide perovskite nanosheets, and the nanocrystal scintillation material is deposited on a substrate as a thin film halide perovskite superstructure; and
a detection device for absorbing the visible photons emitted by the scintillation material,
wherein the scintillation material has a photoluminescence quantum yield (PLQY) of about 60% or more and exhibits a spatial resolution of about 0.21 mm or less.
