Schematic illustration of the structure design of lanthanide-perovskite core@shell nanoparticles for detection of X-ray, UV, and NIR photons. Lanthanide doped upconversion nanocrystals are coated with a layer of mSiO2 shell and organic–inorganic lead-halide perovskite nanocrystals are in situ synthesized inside the pores of mesoporous mSiO2 [212].
