Effect of Synthesis Temperature on the Morphology of ZnO Nanoparticies Obtained via a Novei Chemical Route

摘要

ZnO as a semiconductor is used in many applications such as gas sensor devices, laser and optoelectronic devices, photocatalysts, solar cells, and varistors. The applications and properties of ZnO nanoparticies highly depend on the size and morphology of these particles In this research ZnO nanoparticies were prepared via chemical bath deposition at various temperatures in order to see the effects of synthesis temperature and also 2-methoxyethanol (2-ME) as a novel solvent on the morphology of obtained nanoparticies. For synthesizing of ZnO nanostructured materials, 2-ME has been highly used in sol-gel process but it is the first time that it is used in the chemical bath deposition process. For this purpose 1 M solutions of zinc acetate dehydrate in 2-ME were prepared and added to the solution of NaOH in the same solvent dropwisely. Monoethanolamine (MEA) was used as surfactant The synthesis temperatures were 30°C, 60°C and 90°C. After filtering and drying, morphologies of obtained nanoparticies were characterized and compared.
