High-refractive index nanoparticles can support strong optical Mie resonances, whose spectral positions depend on the particle size. One of these materials is lead halide perovskite, which is a family of materials prospective for light emission. In this work, we demonstrate that a resonant perovskite cubic nanoparticle can be used to control the light emission via the Purcell effect. We present a theoretical study of the dependence of the radiation properties on size and the position of emission source in the particle. The calculations reveal an average Purcell factor enhancement for resonance nanoparticles up to 8, leading to the optimization of the emission quantum efficiency. This is important for the creation of highly efficient perovskite light-emitting devices.
