Abstract: In the present research work, the newest economic method for synthesis of ZnO nanopowder has been carried out via solochemical processing from an aqueous solution of a zinc-containing complex. The results obtained from XRD and TEM show that the nanoparticles are single crystals and have elongated particulate shape with a narrow size distribution. Solochemical processing can thus be an attractive method for industrial production of the nanopowders. The highly textured ZnO thin film with a preferred (002) orientation was also prepared by Two-Stage Chemical Deposition (TSCD), using an aqueous solution containing zinc complex on a soda-lime glass substrate. The films were characterised by XRD, SEM, EDAX, optical spectrophotometer and FTIR to justify the suitability for commercial device quality.

Keywords: zinc oxide; two-stage chemical deposition; TSCD; nanograins; optical transmission; doping; nanopowders; nanolayers; nanomanufacturing; nanotechnology; solochemical processing; nanoparticles.
