Abstract Cesium methylammonium lead iodide (Cs x MA 1− PbI 3 ) nanocrystals were obtained with a wide range of A‐site Cs‐MA compositions by post‐synthetic, room temperature cation exchange between CsPbI and MAPbI nanocrystals. The alloyed Cs retain their photoactive perovskite phase incorporated content, , as high 0.74 the expected composition‐tunable photoluminescence (PL). Excess oleate from reaction mixture in nanocrystal dispersions was necessary to obtain fast exchange. transformation...

The use of metal oxide nanoparticles as anticancer agents is great interest due to their unique properties that allow targeted delivery at low concentrations with minimal toxicity healthy cells. In this work, CdO-CuO-ZnO mixed nanocomposites were synthesized by the co-precipitation method, and structural optical properties, along activity, investigated. samples characterized X-ray diffraction (XRD), total reflection fluorescence (TXRF), transmission electron microscopy (TEM), selected area...

We report a simple method to prepare colloidal trimetallic (Ni-Cu)@Ag core@shell nanoparticles (NPs) without stabilizing materials. Experimental evidence was found for the successful synthesis of these NPs using X-ray diffraction (XRD), optical spectroscopy, and high-resolution transmission electron microscopy (HRTEM). The presence core metals (Ni Cu) confirmed by elemental analysis total reflection fluorescence (TXRF) analysis. In addition, absorption spectra prepared samples exhibited...

The main goals of this study are to synthesize a mixed metal oxide nanocomposite (NC), CdO-CuO-Co3O4, and analyze its structural, morphological, optical, electrical properties using X-ray diffraction (XRD), total reflection fluorescence (TXRF), transmission electron microscopy (TEM), diffuse reflectance spectroscopy (DRS), DC resistivity. According the XRD analysis, CuO nanoparticles (NPs) have monoclinic structure, while CdO Co3O4 cubic structures. TEM images revealed decrease in particle...

Tetragonal superlattices of orientationally ordered, cube-shaped, perovskite CsPbI3 nanocrystals were annealed with hexane vapor and characterized in situ grazing incidence small- wide-angle X-ray scattering (GISAXS/GIWAXS). The superlattice expands all directions periodic order is retained the c-direction orthogonal to substrate, while in-plane orientational eventually lost. tetragonal structure nanocrystal recovered after removing solvent vapor. crystal remains unaffected throughout...
