Morphological control and optical properties of nanocrystalline ZnO powder from precipitation method
Nanocrystalline ZnO powders have been synthesized by using zinc acetate dihydrate and PVP as starting materials. The calcined powders in air at 600oC for 1 hour have been characterized by XRD, indexing the wurtzite or hexagonal structure with the smallest crystallite size of ~ 44.76 nm, and lattice...

| description | Nanocrystalline ZnO powders have been synthesized by using zinc acetate dihydrate and PVP as starting materials. The calcined powders in air at 600oC for 1 hour have been characterized by XRD, indexing the wurtzite or hexagonal structure with the smallest crystallite size of ~ 44.76 nm, and lattice parameters a and c of 0.3249 and 0.5204 nm, respectively at 3x10-4 M PVP. The SEM images show that the morphology has been changed from plate-like to small rod shape when adding PVP to solutions and the morphology has tended to be monosized at higher PVP concentration. The smallest grain sizes of ZnO powders are ~ 130 nm at 3x10-4 M PVP. The optical band gap of all ZnO powders in this study varied between 3.218-3.229 eV. |
