Silver nanoparticles (AgNPs) have happened synthesised via green route utilizing two different plant extracts: Azadirachta indica (Neem) and Tinospora cordifolia (Giloe) leaves extracts. The composition of AgNPs has been noticed from the colour change of the solution and is further habitual by UV-Vis Spectroscopy. Optical properties of synthesized samples have happened carried out utilizing UV–VIS spectrophotometer. For Ag- A. indica NPs, the absorbance maximum occurs at 440 nm and the equivalent absorbance peak occurred at 345 nm in the case of Ag- T. cordifolia NPs. Optical band breach energy has existed estimated utilizing Tauc’s relation and differences of band gap strength at different opportunity intervals were analysed for the AgNPs samples able using Azadirachta indica (Neem) as well asTinospora cordifolia (Giloe) leaves extracts. Particle capacity has been establish to decrease with opportunity for Ag- A. indica NPs whereas piece size increases accompanying time for Ag- T. cordifolia NPs. The combined Ag NPs act as a incentive for the degradation of methylene vulgar (MB) dye under visible light. The portion of degradation was found expected 87.56% within 45 notes of exposure to apparent light.
