Umadevi, S. Kavitha, P. Vanelle, T. Terme] Optical absorption and fluorescence emission techniques were employed to investigate the size effects of silver nanoparticles (Ag NPs) on 1,4-dihydroxy-3-methylanthracene-9,10-dione (DHMAD). Silver nanoparticles of different sizes were prepared by Creighton method under microwave irradiation. The prepared Ag NPs show the surface plasmon band around 400nm. Fluorescence quenching of DHMAD by Ag NPs was found to increase with an increase in the size of Ag NPs. The fluorescence quenching is explained by resonant energy transfer mechanism between DHMAD and Ag NPs, orientation of DHMAD on silver nanoparticles through chemisorptions. The Stern-Volmer quenching constant and Benesi-Hildebrand association constant for the above system were calculated. DFT calculations were also performed to study the ground and excited state behavior of DHMAD and DHMAD + Ag system.
