Ultracompact sources of circularly polarized light are important for classical and quantum optical information processing. Conventional approaches generating chiral emission restricted to excitation power ranges fail provide high-quality radiation with perfect polarization conversion. We used the physics quasi-bound states in continuum demonstrate efficient controllable from resonant metasurfaces. Exploiting intrinsic chirality giant field enhancement, we revealed how simultaneously modify control spectra, patterns, spin angular momentum photoluminescence lasing without any injection. The superior characteristics promise multiple applications nanophotonics optics.

Abstract Electroluminescence efficiencies and stabilities of quasi-two-dimensional halide perovskites are restricted by the formation multiple-quantum-well structures with broad uncontrollable phase distributions. Here, we report a ligand design strategy to substantially suppress diffusion-limited disproportionation, thereby enabling better control. We demonstrate that extending π-conjugation length increasing cross-sectional area enables perovskite thin films dramatically suppressed ion transport, narrowed distributions, reduced defect densities, enhanced radiative recombination efficiencies. Consequently, achieved efficient stable deep-red light-emitting diodes peak external quantum efficiency 26.3% (average 22.9% among 70 devices cross-checked) half-life ~220 2.8 h under constant current density 0.1 12 mA/cm 2 , respectively. Our also exhibit wide wavelength tunability improved spectral stability compared existing diodes. These discoveries provide critical insights into molecular crystallization kinetics low-dimensional semiconductors for devices.

There is increasing interest in the study of chiral degrees freedom occurring matter and electromagnetic fields. Opportunities quantum sciences will likely exploit two main areas that are focus this Review: (1) recent observations chiral-induced spin selectivity (CISS) effect molecules engineered nanomaterials (2) rapidly evolving nanophotonic strategies designed to amplify light–matter interactions. On one hand, CISS underpins observation charge transport through nanoscopic structures favors a particular electronic orientation, resulting large room-temperature polarizations. Observations suggest opportunities for control design fabrication devices from bottom up, with atomic-scale precision molecular modularity. other chiral–optical effects depend on both spin- orbital-angular momentum photons could offer key advantages all-optical information technologies.

Chiral inorganic nanostructures strongly interact with photons changing their polarization state. The resulting circularly polarized light emission (CPLE) has cross-disciplinary importance for a variety of chemical/biological processes and is essential development chiral photonics. However, the effects are often complex interpretation dependent on several structural parameters nanostructure. CPLE in nanostructured media multiple origins optical typically convoluted into single output. Analyzing data obtained nanoclusters, nanoparticles, nanoassemblies, nanocomposites from metals, chalcogenides, perovskite, other nanostructures, it shown here that there distinct groups nanomaterials which dominated either by luminescence (CPL) or scattering (CPS); also many they comparable. following points demonstrated: 1) CPL CPS contributions involve light-matter interactions at different levels; 2) contribution especially strong microparticles, composites; 3) engineering materials requires synergistic implementation effects. These findings expected to guide technological fields, including 3D displays, information storage, biosensors, spintronics, biological probes.
