Abstract
A well-developed Zinc Oxide Nanorod (ZnO-NR) morphology is synthesized via hydrothermal technique. Enhanced surface morphology of SERS substarte is created by using RTA followed by thermal evaporator resulting in gold nanodot pattern on ZnO-NR, based on schottky junction platform. Which are suitable platform & morphology for desired enhanced as well as less defect substrate. Synthesized hexagonal ZnO-NR grown with 3μm length, ~150nm diameter and density 100-NR per μm2. Quantified FE-SEM results shows roughness enhancement with gold coating is possible using RTA treatment and Raman analysis shows excellent signal enhancement, which is quite useful for producing practical high sensitive, stable SERS substrate for sensor applications.
