The fluorescence spectrum of I-naphthol was observed, as a function of time, during the sol to gel to xerogel reaction of a mixed system composed of tetraethyt orthosilicate and diisobutoxyalumino triethoxy silane (silicon to aluminium ratio of approximately 9 : 1) catalysed by HCI. It was found tha
