چکیده
Halide perovskites have attracted considerable attention in next-generation solid-state lighting and displays owing to their outstanding optoelectronic properties. Over the past few years, perovskite light-emitting diodes (LEDs) achieved high external quantum efficiencies of >20% with active layers showing photoluminescence close unity. This paper reviews historical breakthroughs recent advancements LEDs near-infrared, red, green, blue emission colors. Critical challenges, including device stability material toxicity, are discussed. Finally, an outlook on white lasing applications based materials is presented.

Metal halide perovskite light emitters.
Twenty years after layer-type metal halide perovskites were successfully developed, 3D metal halide perovskites (shortly, perovskites) were recently rediscovered and are attracting multidisciplinary interest from physicists, chemists, and material engineers. Perovskites have a crystal structure composed of five atoms per unit cell (ABX3) with cation A positioned at a corner, metal cation B at t...
متن کاملA lead-halide perovskite molecular ferroelectric semiconductor
Inorganic semiconductor ferroelectrics such as BiFeO3 have shown great potential in photovoltaic and other applications. Currently, semiconducting properties and the corresponding application in optoelectronic devices of hybrid organo-plumbate or stannate are a hot topic of academic research; more and more of such hybrids have been synthesized. Structurally, these hybrids are suitable for explo...
متن کاملUltrathin Colloidal Cesium Lead Halide Perovskite Nanowires.
Highly uniform single crystal ultrathin CsPbBr3 nanowires (NWs) with diameter of 2.2 ± 0.2 nm and length up to several microns were successfully synthesized and purified using a catalyst-free colloidal synthesis method followed by a stepwise purification strategy. The NWs have bright photoluminescence (PL) with a photoluminescence quantum yield (PLQY) of about 30% after surface treatment. Large...
متن کاملMetal halide perovskite nanomaterials: synthesis and applications
Nanomaterials refer to those with at least one dimension being at the nanoscale (i.e. <100 nm) such as quantum dots, nanowires, and nanoplatelets. These types of materials normally exhibit optical and electrical properties distinct from their bulk counterparts due to quantum confinement or strong anisotropy. In this perspective, we will focus on a particular material family: metal halide perovs...
متن کاملHybrid Lead Halide Iodide and Lead Halide Bromide in Efficient Hole Conductor Free Perovskite Solar Cell
In this work we used CH3NH3PbInBr3−n (where 0 ≤ n ≤ 3) as hole conductor and light harvester in the solar cell. Various concentrations of methylammonium iodide and methylammonium bromide were studied which reveal that any composition of the hybrid CH3NH3PbInBr3−n can conduct holes. The hybrid perovskite was deposited in two steps, separating it to two precursors to allow better control of the p...
