Sažetak
Zinc oxide (ZnO) is an important technological material due to its excellent chemical, electrical and optical properties. It can be applied in the production of paints, rubbers, cosmetics, catalysts, gas sensors, varistors, LEDs, acoustic wave devices, etc. In all cases the particle morphology and size are important parameters for specific applications of ZnO. In the present work ZnO particles were precipitated at 90 °C by hydrolysis of zinc acetylacetonate (Zn(acac)2) in water at pH~9 to pH~5. Hydrolyses were also performed for different ratios of Zn(acac)2 : Na-citrate. In dependence on the precipitation conditions different shapes and sizes of ZnO particles were obtained. The correlation between these ZnO particles and their FT-IR and Raman spectra were investigated. In the presence of Na-citrate, a plate-like precursor was obtained and spectroscopy showed a coordinated citrate group at the surface of the particles. Upon heating of this precursor at 300 °C, nanosize and monodisperse ZnO particles were produced.
