N2 - The objective of the study was to evaluate the effect on the stability of the silver nanoparticles synthesized by chemical route, according to the variation of the time of exposure of the luminous intensity. Two cases were evaluated by UV-Vis spectrophotometry, the first for colloidal solution, which showed its absorbance peak at 434 nm, typical for silver nanoparticles with spherical morphology; in a second case for colloidal solution under constant light intensity exposure (4409 lux) with times ranging from 15 hours to 48 hours. The results suggest the increase of the diameter of the nanospheres as a function of the increase of time luminous exposition, alsos an increase of the absorbance, which indicates a possible incomplete reaction and a greater production.
