Micropoly method for plasmonic silver nanorods synthesis

摘要

MicroPoJy Method for Plasmonic Silver Nanorods Synthesis is an industrially applicable method to synthesize uniform silver nanorods. MicroPoly method is a microwave modified form of conventional Polyol process which is industrially viable, cost effective and provides an excellent opportunity to researchers and manufacturers to synthesize large quantities of silver nanorods in relatively less time (1-2 hrs) as compared to conventional Polyol process which takes almost 5 hours. Synthesized silver nanorods were characterized using X-ray diffraction technique (Drawing 1), scanning electron microscopy (Drawing 2) and atomic force microscopy (Drawing 3), and UV visible spectroscopy (Drawing 4). These results confirm the formation of crystalline face centered cubic lattice of silver with average width of 300nm and length between 500nm to 5 u.m.Plasmonic absorption bands around 575nm, 450nm and 375nm were observed in absorption spectra (Drawing 5). which are required to use silver nanorods in nano-antennas, sub-wavelength waveguides and efficient solar cells.
