“…Usually, the physical origin of broadband WL emission based on HOIMs is attributed to STEs in a highly distorted inorganic sublattice resulting from strong electron–phonon coupling. − ,− ,, However, a few recent examples attribute the broadband emission to the coexistence of STEs PL peak on inorganic units and a fluorescence peak from emissive centers of the organic molecules, which combine to form a broadband emission covering the entire visible spectrum. ,− On the other hand, our recent report on photophysical properties of some 0D HOIMs based on group 12 metals (Zn and Cd) showed that broadband emission could be the consequence of an exciton localization on the aromatic organic molecular cations . Here, to investigate the origin of the broadband luminescence for 1 and 2 , we also measured the room-temperature PL and PLE spectra of the organic salt 4AMP.…”

Low-dimensional hybrid organic–inorganic materials (HOIMs) are being widely investigated for their unique optoelectronic properties. Some of them exhibit broadband white-light (WL) luminescence upon UV excitation, providing a potential for the fabrication of single-component white-light-emitting diodes. Here, we report new examples of low-dimensional HOIMs, based on 4-aminopyridinium (4AMP) and group 12 metals (Hg and Zn), for single-component WL emission. The 4AMP cation containing structures feature HgBr4 and ZnBr4 isolated tetrahedra in (C5H7N2)2HgBr4·H2O (1) and (C5H7N2)2ZnBr4 (2), respectively. The presence of isolated molecular units in the zero-dimensional structures results in strongly localized charges and bright WL luminescence with corresponding Commission Internationale de l’Eclairage color coordinates of (0.34, 0.38) and (0.25, 0.26), correlated color temperatures of 5206 K (1) and 11 630 K (2), and very high color rendering indexes (CRI) of 87 (1) and 96 (2). The visibly bright WL emission at room temperature is corroborated with high measured photoluminescence quantum yield values of 14.87 and 19.18% for 1 and 2, respectively. Notably, the high CRI values for these new HOIMs exceed the commercial requirements and produce both “warm” and “cold” WL depending on the metal used (Hg or Zn). Based on temperature- and powder-dependent photoluminescence (PL), PL lifetimes measurements and density functional theory calculations, the broadband WL emission is assigned to the 4AMP organic molecules emission and self-trapped states.

“…Enhanced electroluminescence. Resulting from the previous demonstration of the enhanced PL from perovksite metaatoms 26 , metasurfaces 31,33,100,102,113,117 , and also electroluminescence from random nanoparticles 87 and photonic crystals 123 , we anticipate the demonstration of electrically-driven metasurface-based perovskite LEDs. This would result in a dynamical control of LED emission and may offer new opportunities for efficient and smart displays.…”

“…Moreover, in situ chemical variation of the perovskites band gap 24,25 and, thus, the spectrum of their luminescence, opens up unprecedented opportunities for reconfigurable nanophotonic devices not achievable with the use of the conventional GaAs platform. As a result, halide perovskite nanoparticles 26 , nanowires 27,28 , microdisks 29 , microplates 30 , nanoscale gratings 31 , and metasurfaces 32,33 are easy to fabricate and process, and they can become a convenient and cheap part of optical circuitry in the near future 34 . Nevertheless, the existing silicon-based platform is much more developed for on-chip integrated photonics 35 , but it is expected to be outperformed by the perovskites in the future.…”

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.

Exciton-polaritons offer a versatile platform for realization of all-optical integrated logic gates due to the strong effective optical nonlinearity resulting from the exciton-exciton interactions. In most of the current excitonic materials there exists a direct connection between the exciton robustness to thermal fluctuations and the strength of exciton-exciton interaction, making materials with highest levels of exciton nonlinearity applicable at cryogenic temperatures only. Here, we show that strong polaronic effects, characteristic for perovskite materials, allow to overcome this limitation. Namely, we demonstrate the recordhigh value of the nonlinear optical response in nanostructured organic-inorganic halide perovskite MAPbI 3 , experimentally detected as 19.7 meV blueshift of the polariton branch under femtosecond laser irradiation. This is substantially higher than characteristic values for the samples based on conventional semiconductors and monolayers of transition metal dichalcogenides. The observed strong polaron-enhanced nonlinearity exists for both tetragonal and orthorombic phases of MAPbI 3 , and remains stable at elevated temperatures.
