✦ Synopsis

In this work we report on the luminescence properties of gold nanorods synthesized by a seed growth method in the presence of cetyltrimethylammonium bromide (CTAB) solutions. We have found that the emission intensity is dependent on the aspect ratio and the degree of dispersivity of the gold nanorods. The observed emission is explained in the term of the enhancement effect of the electric fields via coupling to the surface plasmon resonance in the rods.
