abstract = {Metal halide perovskites are revolutionizing X-ray
detection through a combination of low cost, solution
processing, favorable optoelectronic properties, and high
stopping power for high-energy ionizing radiation. While
perovskite single crystals and polycrystalline wafers are
considered direct X-ray converters, most medical X-ray
applications are based on scintillators that shift
high-energy radiation into the visible. Several materials
are on the market, but demonstrations based on CsPbBr3
nanocrystals, possibly embedded in a matrix material or
combined with organic molecules as luminescent species,
highlight their competitiveness with established
scintillators in terms of radioluminescence yield and
transient behavior. Major hurdles that perovskite
nanocrystal scintillators must overcome are environmental
stability and toxicity. While there are still few examples
of high-performance lead-free perovskite nanocrystal
scintillators, microcrystalline perovskites are emerging
with promising properties, reduced toxicity, and significant
Stokes shifts to avoid reabsorption of emission in thick
films. Thus, the near future of perovskite nanocrystal
scintillator materials will primarily be the adoption of
recipes for materials with proven properties in
microcrystalline form. The nanocrystal colloidal solutions
will facilitate the large-scale printing of homogeneous and
scattering-free films to obtain high contrast and spatial
resolution X-ray images by scintillation},
