Abstract

We developed a procedure for the electrodeposition of fluorescent silicon nanomaterial from silicates on conducting substrates. The electrodeposion solution used is a solution of sodium metasilicon salts (Na2SiO3) in HF/H2O2. When a positively biased platinum substrate is immersed in the bath, a current is drawn and a thin fluorescent coating is formed on the substrate. We discuss the results in terms of current-induced nucleation of silicon nanostructures.
