PREPARATION OF FULLERENCE DOPED SILICA AEROGELS AND THE STUDY OF PHOTOLUMINESCENCE PROPERTIES

Abstract This paper introduces the preparation of fullerence doped silica aerogels by “chemically doped” and sol gel process.The infrared spectra and time of flight mass spectra show that C 60 were successfully incorporated into the silica aerogel and the structures were retained in the fabrication process.Photoluminescence spectra shows that fullerence doped silica aerogels exhibit broad visible light under Ar + laser(488nm).The photoluminescence is blue shifted compared with pure C 60 .In this paper, we give an explanation to this blue shift.
