Abstract
Effect of temperature on the formation of silver nanorods (AgNRs) synthesized using polyol method has been investigated. In this experiment, materials were used silver nitrate (AgNO ) as main raw material, ethylene glycol (EG) as a solvent, small amount of sodium chloride (NaCl) as a mediated agent, while polyvinyl alcohol (PVA) as a capping agent to assist the growth of AgNRs. To apply a constant temperature at each synthesis process, an Erlenmeyer flask containing the sample was immersed in a controllable magnetic stirrer oil bath. It is found that the presence of heat as represented by the temperature of oil bath has been shown to have a strong impact on the AgNRs formation. The scanning electron microscope (SEM) confirmed uniform and high density of AgNRs when the oil bath temperature during polyol process was 140°C. In the same condition, the UV-vis spectra also confirmed formation process of AgNRs with appearance of the transverse plasmon peak about 350 nm. Finally, the X-ray diffraction (XRD) pattern represented that the final product of AgNRs was highly crystallized.
