The ratio of HAuCl and naphthazarin played a vital role in controlling the shape and size of gold nano- particles. Three samples with significant differences in sizes (range of 10–200 nm) have been prepared through increasing the initial naphthazarin/HAuCl molar ratio from 50 to 200. The size, distribution, and formation of gold nanoparticles were confirmed by transmission electron microscopy, Fourier transform infrared spectroscopy, and UV– Visible absorption spectroscopic measurements.
