The Influence of the Film Deposition of Metals on the Composition and Optical Characteristics of Porous Silicon for Use in Hydrogen Energy

The paper studies the composition and optical properties of advanced composites based on porous silicon with deposited transition metals and indium and tin by a sol-gel process. It is shown that the deposition of films of metals of the iron group enhances the photoluminescence intensity and stabilizes it in time, while the deposition of tin and indium has virtually no effect on the optical characteristics of the porous layer. The paper shows coating the surface of the sample by metal oxide film saves hydrogen in the pores.
