摘　　要：利用开环态双光子吸收转化荧光光谱、荧光淬灭光谱等探究了二芳基乙烯的光学记录特性及参数,得到其非线性吸收系数为3.46×10^(-13) m/W,双光子吸收转化的阈值功率密度为107.36GW/cm^2,荧光淬灭的阈值功率密度为2.89GW/cm^2。基于所得到的测试参数,理论计算出其在超分辨光存储中的分辨率可达60.0nm,并设计了一种基于二芳基乙烯的双光子双光束超分辨光存储信息记录和读出方法。研究结果表明,二芳基乙烯具有光诱导-光抑制、非线性吸收及荧光淬灭等特性,是一种优异的超分辨光存储备选材料。The optical recording properties and parameters of dithienylethene are investigated by the fluorescence spectrum conversed by ring-opening two-photon absorption and the fluorescence-quenching spectrum.Its nonlinear absorption coefficient is 3.46×10^-13 m·W^-1,the power density threshold of the two-photon absorption conversion is 107.36 GW·cm^-2,and the power density threshold of the fluorescence quenching is 2.89 GW·cm^-2.Based on these measurement parameters,a resolution of 60.0 nm in super-resolution optical storage is theoretically calculated and obtained,and a kind of recording and reading method for the information of the two-photon-dual-beam superresolution optical storage based on diarylethene is designed.The results indicate that,the dithienylethene possesses the characteristics such as photo-induction-photo-inhibition,nonlinear absorption and fluorescence-quenching,and is an excellent optional material for the super-resolution optical storage.
