Abstract
Research on materials with perovskite crystal symmetry for photonics applications represent a rapidly growing area of the photonics development due to their unique optical and electrical properties. Among them are high charge carrier mobility, high photoluminescence quantum yield, and high extinction coefficients, which can be tuned through all visible range by a controllable change in chemical composition. To date, most of such materials contain lead atoms, which is one of the obstacles for their large-scale implementation. This disadvantage can be overcome via the substitution of lead with less toxic chemical elements, such as Sn, Bi, Yb, etc., and their mixtures. Herein, we summarized the scientific works from 2016 related to the lead-free perovskite materials with stress on the lasing and lighting applications. The synthetic approaches, chemical composition, and morphology of materials, together with the optimal device configurations depending on the material parameters are summarized with a focus on future challenges.

Summary
The growing request of the market makes demands on modern photonics materials such as ability for miniaturization, higher efficiency, tunable and controllable optical and electrical properties, and stable performance. The solution of these problems will result in increased performance of the photovoltaic and optoelectronic devices based on the perovskite active media. We want to highlight in this piece some of the recent review papers and finding novel synthetic routes for lead-free perovskite materials. Information on lead-free organic-inorganic halide perovskite a recent review [18]The by authors. In the present mini-review, we show recent development in the field of lead-free perovskite materials application in light-emitting devices. We discuss recent progress in LED and lasing technologies over the perspectives of the development of the lead-free perovskite materials for photovoltaic applications
