Seed-mediated method is a general procedure for the synthesis of gold nanorods(Au NRs) who developed Murphy et al. and El-Sayed et al. Many of the interesting optical properties of Au NRs are determined by the position of their LSPR peak, which is largely governed by the aspect ratio of Au NRs. In this experiment, we have controlled parameters to tuned from visible to infrared by tuning their aspect ratio. As a result, we show the tunable plasmon bands depending on the volume/concentration of the chemical reagents by using hydroquinone as a reducing agent in the presence of silver nitrate and the longitudinal LSPR peak is still in the range of Vis-NIR even if the size of Au NRs is less than 20nm in length. And previously known LSPR peaks of Au NRs are less than 900nm or more than 1200nm. But we also synthesize high aspect ratio Au NRs with peaks more than 1,200nm by using co reducing agent.
