Abstract
The first observation of fullerene C60 ultraviolet photolysis in hexan e solution was published two years ago 1!. Similar further experiment s realized with an ultraviolet lamp and solar light gave inconsistent results with ambiguous interpretations. We report the unexpectedly fas t and efficient degradation of the fullerenes in n-hexane solutions, i nduced by an XeCl-excimer laser. Well-defined experimental conditions and good reproducibility in these experiments allow us to estimate the minimal value of the quantum yield of fullerene photolysis.
