应用倍频 Ｎｄ：ＹＡＧ激光（波长为 ５３２ ｎｍ，脉宽为 ８ ｎｓ）研究了 ２种新合成的 Ｃ_(６０)衍生物 Ｃ_(６０)ＣＨ_２和Ｃ_(６０)ＨＲ（Ｒ＝Ｃ_６Ｈ_５ＣＯ－）甲苯溶液的光限幅性质．Ｃ_(６０)ＨＲ的光限幅效应与Ｃ_(６０)相比稍差，而Ｃ_(６０)ＣＨ_２的光限幅效应与Ｃ_(６０)相近，并具有更低的限幅幅值．
Two newly synthesized C 60 derivatives of C 60 and C 60 HR (R = C 6 H 5 CO-) were studied by double frequency Nd: YAG laser with wavelength of 532 nm and pulse width of 8 ns. Optical Limiting Properties of Solutions. The optical limiting effect of C_ (60) HR is slightly worse than that of C_ (60), while the optical limiting effect of C_ (60) CH_2 is similar to that of C_ (60) and has a lower limiting amplitude.
