Green Synthesis of Silver Nano-Particles at Room Temperature
Nano-particles can be prepared easily by different chemical, physical and biological approaches. But the biological approach is the most emerging approach of preparation, because, this method is easier than the other methods, eco-friendly and less time consuming. In this work green synthesis was done by using the aqueous solution of Azadirachta indica (Neem) and Murraya koenigii (Curry) leaf extract and AgNO3. Silver was of a particular interest for this process due to its evocative physical and chemical properties. A fixed ratio of plant extract to metal ion was prepared and the colour change was observed which proved the formation of nano-particles. The nano-particles were characterized by UV-Vis spectroscopy and X-ray diffraction technique. The UV-VIS spectroscopy shows sharp absorbance around 440 nm, it also reveals the band gap to be around 2.5 eV and 3.2 eV for Ag nano-particles synthesized using Neem leaves and curry leaves respectively. The particle size was found to be 35 nm and 21 nm for Ag nano-particles synthesized using Neem leaves and curry leaves respectively.
