Detection of hazardous volatile organic and inorganic species is a crucial task for addressing human safety in the chemical industry. Among these species, there are hydrogen halides (HX, X = Cl, Br, I) vastly exploited numerous technological processes. Therefore, development cost-effective, highly sensitive detector selective to any HX gas particular interest. Herein, we demonstrate optical detection chloride with solution-processed halide perovskite nanowire lasers grown on nanostructured...
Abstract Halide perovskite lasers based on CsPbBr 3 micro‐ and nanoscale crystals have demonstrated fascinating performance owing to their low‐threshold lasing at room temperature cost‐effective fabrication. However, chemically synthesized thin films of usually rough polycrystalline morphology along with a large amount crystal lattice defects and, thus, are mostly utilized for the engineering light‐emitting devices. This obstacle prevents usage in many photonic applications. Here, protocol...

Hyperbolic metamaterials are a family of nanophotonic architectures allowing for the unique control photonic local density states. Such property makes prospective to use them with light-emitting objects or apply as meta-electrodes optoelectronic devices, where recombination properties plays decisive role. On other hand, layered quasi-2D halide perovskites (Ruddlesden–Popper phase) attract high attention due their low cost, broadband spectral tunability, and outstanding properties. Here, we...
Abstract Perovskite light-emitting diodes (pero-LEDs) is a rapidly developing technology that supposed to supersede existing ones in the near future. In comparison with organic and A III B V analogues, pero-LEDs possess following advantages: very narrow spectral linewidth of electroluminescence (EL), tunability whole visible range possibility cost-effective large-scale fabrication by means wet chemistry techniques. CsPbX 3 (X = Cl, Br, I) are most robust perovskites suitable for LEDs...
Inorganic perovskites of CsPbX3 (X = Cl, Br, I) type are excitonic semiconductors for optoelectronics and nanophotonics showing outstanding optical properties that can be controlled via their chemical composition tuning. Pure chloride, bromide iodide phases such materials exhibit intense photoluminescence with FWHF 12-30 nm (FWHM – full width at half maximum) peaked 420, 525 710 nm, respectively. In the meanwhile, mixed-halide aimed to fill these gaps demonstrate emission in whole visible...

Most of the planar light-emitting devices have a multilayer structure that consists electron-transporting (ETL), hole- transporting (HTL), and emissive (EL) layers. Usually, manufacturing with complex architecture is related to employment expensive materials high-tech processes such as vacuum deposition. Therefore, cost-effective large- scale wet chemical production efficient single-layer remains hot topic in field optoelectronics. Although finding suitable semiconducting material for...
