Résumé :

In this paper, we report the synthesis of ZnO nanogranules by a solid state mixing of zinc nitrate tetrahydrate ZnO(NO3)2 with citric acid monohydrate C6H8O7, followed by aging and calcination at different temperatures of 400°C to 600°C. The crystallinity, structure and morphology of as prepared ZnO-nanocrystals have been characterized using powder X-ray diffraction (XRD), scanning electron Microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). Optical properties of ZnO nanoparticles were also studied using an ultraviolet–visible (UV–vis) spectrophotometer.
