Abstract
A post-etch treatment for enhancing and stabilizing the photoluminescence (PL) from a porous silicon (PS) substrate is outlined. The method includes treating the PS substrate with an aqueous hydrochloric acid solution and then treating the PS substrate with an alcohol. Alternatively, the post-etch method of enhancing and stabilizing the PL from a PS substrate includes treating the PS substrate with an aqueous hydrochloric acid and alcohol solution. Further, the PL of the PS substrate can be enhanced by treating the PS substrate with a dye. Furthermore, the PS substrate can be metallized to form a PS substrate with resistances ranging from 20 to 1000 ohms.
