Abstract

The growth of gold (Au) nanoparticles using a modified seed mediated growth technique which is suitable for surface plasmon resonance (SPR) applications is demonstrated. Unlike the conventional method, the formation of consistent-sized gold nanoparticles was successfully achieved without adding a reduction agent into the growth solution. We analysed the UV-Vis, FESEM and EDX results for samples prepared on both FTO and ITO substrates. The effect of growth time and the concentration of citrate ions on the morphology and SPR peaks are also discussed. Gold nanoparticles with consistent grain size of 20 nm can be obtained with 2 hours growth time with citrate ion concentration of 0.01 M which gives a SPR peak of 551 nm and absorbance of 0.063. In conclusion, we have proved that this modified technique is suitable to produce consistent gold nanoparticles.
