Size Controlled Synthesis Of Gold Nanoparticles Using ...
The final size of the particles would depend on the size of the ‘seed’ and the amount of the precursor ions to be reduced on them (Schmid, 1992). Therefore, in principle, the smaller is the starting seed, the lower will be the desired size limit of the particles. It allows preparing particles over a broad size range. Smaller ... Retrieve Doc
