This article explores the synthesis and characterization of zinc oxide nanoparticles produced via the sol-gel process, a method known for its ability to control particle size and morphology. The resulting nanoparticles exhibit a quartzite structure, as confirmed by X-ray phase analysis, with an average crystallite size of 17 nm. Hydrodynamic measurements, conducted using dynamic light scattering techniques, revealed an average particle radius of approximately 70 nm, indicating some degree of agglomeration in the colloidal solution. Scanning electron microscopy further supported these findings, showing that the zinc oxide nanoparticles tend to form polymorphic nano-sized agglomerates. The observed aggregation behavior is significant, as it may influence the material’s properties and potential applications in fields such as catalysis, photovoltaics, and sensor technology. This study not only highlights the effectiveness of the sol-gel process in producing zinc oxide nanoparticles with controlled sizes but also provides insights into their aggregation tendencies, which are crucial for optimizing their functional performance in various applications.
