摘　　要：报导和总结了运用两种先驱体配方和溶胶－凝胶的工艺过程，成功地把富勒烯物质掺入到各种凝胶介质中。比较了采用不同方法的优缺性。富勒烯处于凝胶介质的微孔及与凝胶介质结构相关联的２种结构状态。分别测定了处于２种结构状态下的紫外－可见光谱及与介质相关联的红外光谱，并进行了比较和讨论。用调Ｑ，ＹＡＧ，５３２ｎｍ波长脉宽为１０ｎｓ的激光作为光源，实现了处于２种结构状态下的光限制效应。讨论了介质对富勒烯物质的结构和性质的影响，这些凝胶块体的抗激光损伤阈值均能达５～６Ｊ／ｃｍ２。We concluded some motheds of fabrication of gels doped with C 60 The precursors and sol-gel processes werechosen and compared The C 60 located in pore of the gel orconnected with gel The UV-Vis and IR spectra of the materials were measured and discussed Using Nd:YAG laser with 10ns pulseduration and 532nm wavelength,the optical limiting behaviors of C 60 in two different structure were demonstrated The matrix affects on C 60 were discussed
