Abstract
The present paper focuses on the obtaining of ZnO in powder form with a limited distribution of the nanoparticle size using different types of surface-active agents and optimizing the synthesis conditions. The coprecipitation process was chosen for the ZnO powder synthesis in the absence and in the presence of surface-active agents, being considered one of the most common synthesis and processing methods for producing nanostructured materials. The use of agents consists in preventing the nanoparticle size growth, but also in stabilizing the aggregation trend effectively by controlling structural features and by reducing the oxygen bridge bonds between particles. The anionic surfactant (SDS sodium dodecyl sulfate) and the cationic surfactant (CTAB cetyltrimethylammonium bromide) were used to modify the size, morphology and surface properties of the precipitated nanoparticles. Based on the structural characterization by FTIR, XRD, morphology by SEM, as well as UV absorption and PL analyses of ZnO in various versions, the significant influence of agents on ZnO particles, as well as the correlation of optical systems properties with particles morphology and size was revealed. The development of this type of material encourages the uses in many applications in nanotechnology, electronics, optics and other areas of modern science and technology.
