摘　　要：报道了Ｃ６０掺杂气凝胶的奇异光致发光现象．利用两种掺杂方法制备了Ｃ６０掺杂ＳｉＯ２气凝胶样品，红外吸收光谱及飞行时间质谱测试表明Ｃ６０分子被成功地掺入ＳｉＯ２气凝胶中．在室温条件下，以Ａｒ＋激光（４８８ｎｍ，１０ｍＷ）激发，观测到Ｃ６０掺杂气凝胶的强可见发光，发光峰位置较纯Ｃ６０明显蓝移。The photoluminescence (PL) properties of C 60 doped silica aerogel samples were reported. The samples were prepared by two different doping methods and were characterized by Fourier transform infrared spectroscopy and time of flight mass spectroscopy. The C 60 doped composites were found to be able to emit intense visible light and its peak was blue shifted obviously compared to that of the pure C 60 , under Ar + laser (488nm,10mW) excitation at room temperature. The influence of doping methods and annealing process on the light emitting properties of the samples was also discussed.
