The development of environmentally friendly technologies in synthesizing materials is of considerable importance for expanding their biological applications. Todays, various types of nanoparticles have been synthesized by the method of green synthesis with a well-defined chemical composition, size, and morphology and their applications in many advanced fields of technology have been studied. This study was performed to find the optimal conditions for the green synthesis of silver nanoparticles from an aqueous extract of lettuce leaves. To find the optimal condition, different concentrations of silver nitrate and aqueous extract, different ratios of aqueous extract and silver nitrate, different light spectra with different concentrations of aqueous extract were studied. The results showed that the aqueous extract containing 20 g of lettuce leaves in 100 ml of distilled water, 1 mM silver nitrate concentration, and 1:1 ratio under blue light for 24 hours had the maximum absorption rate among other samples. The results of X-ray diffraction spectroscopy also confirm the crystallization of nanoparticles in this sample.
