Abstract

The interaction of CO₂ laser radiation with mixtures of silane and molybdenum hexacarbonyl (vapor) results in solid Si/C/O/Mo material and various gaseous compounds (mainly CO). The XPS, SEM and IR spectral analysis of the deposit pointed out an organosilicon polymer structure, with a composition that is strongly affected by SiH₄ partial concentration. Possible routes involved in the SiH₄-photosensitized decomposition of Mo(CO)₆ are discussed. The laser technique can serve as an efficient method for creating metal-modified organosilicon polymers for membrane modification.
