Highly Crystalline pure and Ag-doped ZnO nanoparticles were prepared using the inexpensive sol-gel synthesis method with the stimulation of transition metal ion surfactant. The prepared pure and Agdoped (Silver doped) ZnO nanoparticles were characterised by various sophisticated techniques like x-ray Diffraction (XRD), Scanning Electron Microscope (SEM), Dynamic Light scattering (DLS), Fourier Transform Infrared Spectroscopy (FTIR), UV-visible absorption, Photoluminescence (PL) and Zeta potential. The result indicates that the average grain size of the prepared nanoparticles was found to be a minuscule 24 nm with a commendable bandgap of 3.21 eV and 1.73 eV respectively. The hexagonal wurzite structures of pure and Ag-doped ZnO at room temperature confirmed the luminescence characteristics of the nanoparticles.

The two mixed halides of barium, barium chloroiodide and barium bromoiodide, were synthesized via a solid-state reaction route. In this article, their powder XRD data are reported. A careful analysis of the X-ray data shows that both BaClI and BaBrI crystallize in the orthorhombic structure. The lattice parameters obtained are a=17.841±0.003 Å, b=8.441±0.001 Å and c=5.642±0.001 Å for BaClI (SG. Pbam, No. 55) and a=13.667±0.002 Å, b=12.012±0.001 Å and c=10.871±0.002 Å for BaBrI (SG. P2221 No. 17).
