Resonant halide perovskite nanoparticles

The hybrid halide perovskites is a prospective material for fa
brication of cost-effective optical devices. Unique
perovskites properties are used for solar cells and different p
hotonic applications. Recently, perovskite-based
nanophotonics has emerged. Here, we consider perovskite like a
high-refractive index dielectric material, which can be
considered to be a basis for nanoparticles fabrication with Mie
resonances. As a result, we fabricate and study resonant
perovskite nanoparticles with different sizes. We reveal, that spherical nanoparticles show enhanced photoluminescence
signal. The achieved results lay a cornerstone in the field of
novel types of organic-inorganic nanophotonics devices with
optical properties improved by Mie resonances.
