Perovskite Materials

We present a new method for soft chemical synthesis of perovskite materials. Perovskite K1-xLixNbO3 powders are produced by an ion-exchange reaction of layered perovskite precursor, K2NbO3F, with lithium chloride in water at room temperature. X-ray diffraction and X-ray fluorescent spectroscopic studies show that a mechanism of the ion-exchange reaction is a self-assembly between the perovskite nanosheets in aqueous solution.

Ion Exchange Reaction

Photoluminescent CdS–CdSe nanocomposites with core–shell structures were obtained via a novel two-step γ-irradiation process followed by a simple ion-exchange reaction at room temperature and under ambient pressure. To fully characterize CdS–CdSe nanocomposites, X-ray photoelectron spectroscopy, UV–vis absorption spectra, and photoluminescence spectra were recorded, as well as powder X-ray diffraction, transmission electron microscopy, and high-resolution electron microscopy, to confirm the presence of the core–shell nanostructure.Key words: core–shell nanostructure, γ-irradiation, ion-exchange reaction.
