All-inorganic cesium lead halide perovskite nanocrystals for photodetector applications.
Herein, we describe simple, fast and reproducible halide ion exchange reactions in CsPbX3 (X = Cl, Br, I) nanocrystals (NCs) at room temperature. Through the simple adjustment of the halide ion concentration, the photoluminescence of these NCs can be tuned over the entire visible region (425-655 nm). Photodetector devices based on entirely inorganic CsPbI3 NCs are demonstrated for the first tim...
متن کاملExtraordinary Interfacial Stitching between Single All-Inorganic Perovskite Nanocrystals
All-inorganic cesium lead halide perovskite nanocrystals are extensively studied because of their outstanding optoelectronic properties. Being of a cubic shape and typically featuring a narrow size distribution, CsPbX3 (X = Cl, Br, and I) nanocrystals are the ideal starting material for the development of homogeneous thin films as required for photovoltaic and optoelectronic applications. Recen...
متن کاملThermal degradation of luminescence in inorganic perovskite CsPbBr3 nanocrystals.
The luminescence properties of inorganic perovskite CsPbBr3 nanocrystals (NCs) with emissions of 492 and 517 nm under thermal annealing treatment were studied by temperature-dependent photoluminescence (PL) spectroscopy. The CsPbBr3 NCs were annealed in vacuum at various temperatures. It was found that the NCs exhibited significant thermal degradation of PL at thermal annealing temperatures abo...
متن کاملLigand Mediated Transformation of Cesium Lead Bromide Perovskite Nanocrystals to Lead Depleted Cs4PbBr6 Nanocrystals.
Lead halide perovskite nanocrystals (NCs) have emerged as attractive nanomaterials owing to their excellent optical and optoelectronic properties. Their intrinsic instability and soft nature enable a post-synthetic controlled chemical transformation. We studied a ligand mediated transformation of presynthesized CsPbBr3 NCs to a new type of lead-halide depleted perovskite derivative nanocrystal,...
متن کاملElectrochemical behaviour of lead in hydrochloric acid solution in the presence of inorganic ions
The electrochemical behaviour of lead electrode in hydrochloride solution containing variousoxo-anions at different concentrations was studied by using of cyclic voltammetry (CV) method.Results obtained show that the addition of these inorganic compounds decreases the anodic andcathodic currents peaks according to the following order: H2PO4- > HPO42-> SO42-. It’s revealedalso that the cathodic ...
