UV laser photolysis of 1,3-butadiyne and formation of a polyoxocarbosilane-doped nanosized carbon

Highly intense ArF laser radiation induced photolysis of gaseous 1,3-butadiyne results in the formation of a number of volatile, highly unsaturated hydrocarbons and efficient deposition of nanosized carbon soot. Minor etching of the reactor silica window by photolytic products allows doping of the depositing carbon soot by nanosized silica and polyoxocarbosilane. Upon heating to 700 °C, the photoproduct converts to partially graphitized carbon containing polyoxocarbosilane.
