中文摘要通过对新合成的芴的一种具有对称性衍生物4-2-(7-(4-氨基苯乙烯基)-9,9-二(2-乙基己基)-9H-芴-2-)乙烯基)苯胺(BASF)的DMF溶液的研究,发现其具有很强三光子吸收频率上转换荧光发射特性,实验测出上转换荧光的波长范围是456-775nm,在510nm处的荧光强度与入射光强的三次方成正比.在0.03mol/L的浓度下就有明显的三光子吸收诱导的光限幅效应.非线性吸收系数和吸收截面分别为y=4.34×10^20 cm^3/W^2和σ3=2.4×10^-39 cm^6/W^2.; Three-photon-absorption-induced frequency up-conversion fluorescence emission has been observed in a solution of 4-2-(7-4-amido styrene)-9, 9-di (2-ethyl hexyl)-9H-fluorene-2-) ethylene) aniline ( BASF) in N, N-dimethylformamide (DMF), pumped with 38ps Q-switched 1064nm laser pulses. The spectral peak of the observed fluorescence emission is located in the 456-775nm range, and the intensity dependence of the visible emission on the IR excitation obeys the cubic law. At higher solute concentration and moderate IR excitation intensity levels, obvious optical limitation behavior has been observed due to three-photon-absorption. The measured nonlinear absorption coefficient and the molecular three- photon- absorption cross section are 4.34 x 10(-20) cm(3) /W-2 and 2.4 x 10(-39) cm(6)/W-2, respectively.
