“…One of the possible applications of the Purcell factor enhancement in perovskite nanoparticles is more efficient optical cooling at the nanoscale. Indeed, as was predicted theoretically 89 , this effect helps to boost internal QY of PL for MAPbI 3 nanoparticles and enhance the absorption of light at pumping wavelength below band gap. As a result, we may expect the cooling down to ∆T ≈-100 K.…”

Meta-optics based on optically resonant all-dielectric structures is a rapidly developing research area driven by its potential applications for low-loss efficient metadevices. Active, light-emitting subwavelengh nanostructures and metasurfaces are of a particular interest for meta-optics, as they offer unique opportunities for novel types of compact light sources and nanolasers. Recently, the study of halide perovskites has attracted an enormous attention due to their exceptional optical and electrical properties. As a result, this family of materials can provide a prospective platform for modern nanophotonics and meta-optics, allowing to overcome many obstacles associated with the use of conventional semiconductor materials. Here we review the recent progress in the field of halide-perovskite meta-optics with the central focus on light-emitting nanoantennas and metasurfaces for the emerging field of active metadevices.

“…Nanostructured lead halide perovskite materials have gained significant attention in the last few years mainly because of their potential for application in the field of electronics and photonics. There are several available reports demonstrating their implementation into light emitting diodes (LED) 1 – 3 , solid-state lasers 4 , solar cells 5 , photodetectors 6 and optical cooling systems 7 . Especially the photoluminescence quantum yields (PLQY) of up to 100% make these nanostructured perovskite materials very interesting 8 .…”

This work reports on an optimized procedure to synthesize methylammonium bromide perovskite nanoparticles. The ligand-assisted precipitation synthetic pathway for preparing nanoparticles is a cost-effective and promising method due to its ease of scalability, affordable equipment requirements and convenient operational temperatures. Nevertheless, there are several parameters that influence the resulting optical properties of the final nanomaterials. Here, the influence of the choice of solvent system, capping agents, temperature during precipitation and ratios of precursor chemicals is described, among other factors. Moreover, the colloidal stability and stability of the precursor solution is studied. All of the above-mentioned parameters were observed to strongly affect the resulting optical properties of the colloidal solutions. Various solvents, dispersion media, and selection of capping agents affected the formation of the perovskite structure, and thus qualitative and quantitative optimization of the synthetic procedure conditions resulted in nanoparticles of different dimensions and optical properties. The emission maxima of the nanoparticles were in the 508–519 nm range due to quantum confinement, as confirmed by transmission electron microscopy. This detailed study allows the selection of the best optimal conditions when using the ligand-assisted precipitation method as a powerful tool to fine-tune nanostructured perovskite features targeted for specific applications.

“…The numerical and analytical modeling revealed that the highest cooling efficiencies for a halide perovskite spherical NP correspond to the excitation of magnetic-type Mie modes. [184] Namely, magnetic octupole at the emission and magnetic quadrupole at absorption allow for cooling a single nanocavity by ∆T ≈ -110 K at realistic conditions. In opposite, GaAs nanoparticles with less efficient PL can not be optically cooled with this mechanism as shown in Fig.…”

Nanophotonics is an important branch of modern optics dealing with lightmatter interaction at the nanoscale. Nanoparticles can exhibit enhanced light absorption under illumination by light, and they become nanoscale sources of heat that can be precisely controlled and manipulated. For metal nanoparticles, such effects have been studied in the framework of thermoplasmonics which, similar to plasmonics itself, has a number of limitations. Recently emerged all-dielectric resonant nanophotonics is associated with optically-induced electric and magnetic Mie resonances, and this field is developing very rapidly in the last decade. As a result, thermoplasmonics is being replaced by all-dielectric thermonanophotonics with many important applications such as photothermal cancer therapy, drug and gene delivery, nanochemistry, and photothermal imaging. This review paper aims to introduce this new field of non-plasmonic nanophotonics and discuss associated thermally-induced processes at the nanoscale.
