摘要：

A study was conducted, to perform seedless and surfactantless room temperature synthesis of single crystalline fluorescent nanostructured gold (Au) nanoparticles. The study also investigated the SERS characteristic and electrocatalytic activity of these single crystalline gold nanoparticles. It was found that the gold nanoparticles were synthesized by the simple mixing of an aqueous solution of 5-hydroxyndole-3-acetic acid (HIAA) and HAuCl4 at room temperature, while stirring the solution for 30 minutes. It was observed that the color of the solution turned to salmon, immediately after mixing, indicating the formation of Au nanoparticles. High-resolution transmission electron microscopy (TEM) images of selected Au nanoparticles investigated their morphology. The study also confirmed that the fluorescence of Au was due to the interband recombination of electron and hole.
