dc.description.abstract	Silver nanoparticles (AgNPs) exhibit unique optical properties due to their localized surface plasmon resonance (LSPR), which is influenced by their size, shape, and synthesis method. This study aims to explore and compare the optical quality of AgNPs synthesized using various plant extracts, assess the impact of nanoparticle size on the dielectric function, and analyze how these size-dependent variations affect optical density and extinction cross-section.We reviewed AgNPs using different plant extracts and evaluated their optical properties, focusing on the real and imaginary parts of the dielectric function. The study determined that the size of the nanoparticles significantly influences their dielectric response, which in turn affects their optical characteristics, including optical density and extinction cross-section. Comparative analysis revealed differences in the LSPR characteristics based on the plant extract used, with certain extracts yielding AgNPs with superior optical properties. The findings indicate that plant extracts play a crucial role in determining the size, shape, and optical quality of AgNPs. Identifying the most effective plant extracts for optimal optical performance can enhance the reproducibility and quality of AgNP synthesis. This study provides valuable insights into optimizing the synthesis of AgNPs for various applications, offering guidelines for selecting plant extracts and improving synthesis protocols to achieve consistent and high-quality nanoparticles.	en_US
