Silver nanoparticles due to their special optical, electrical and catalytic properties, which are related to their shape, size and chemical surface, have vast applications in various sections of science and industries. So, beside the control over their size, control of their shape is also necessary [1]. Among nanoparticles, silver nanoparticles with features such as; electronic conductivity, high temperature stability, chemical stability, high catalytic activity, anti-bacterial properties and low cost are a suitable choice for applications in a wide range of industries [2]. Silver nanoparticles significantly enhance the peaks in optical systems, which leads to the increment of these system’s efficiencies in measurement and detection of various materials. Several methods are used for synthesis of nanoparticles in different shapes and sizes [3]; laser erosion, thermal decomposition of microwave with reverse micelle sol-gel, sonochemical reduction, photochemical reduction and chemical reduction. In this study, different morphologies and sizes of silver nanoparticles, through variations in the experiment conditions, were successfully synthesized. Distribution and morphology of the particles were determined by SEM, DLS and UV-Vis tests. Catalytic properties of silver nanoparticles were evaluated in quantitative luminescence interactions. Based on the results, by reducing the size of the nanoparticles the intensities of the peaks of quantitative luminescence are increased. The best size and morphology were chosen based on the comparison of peak’s intensities in quantitative luminescence system.
