一种有机化合物双光子荧光现象的实验研究

Two photon Absorption Induced Fluorescence in an Organic Compound

利用激光与有机化合物苯乙烯基并三苯溶液相互作用，我们得到了该化合物的单光子及双光子吸收荧光光谱，溶剂为二氧杂环已烷，在一定的波长范围内测量了双光子吸收的荧光偏振比率。实验结果证明了该有机化合物的激发态可通过单光子或双光子吸收获得，并指出激发态具有Ａｇ对称性。

Using the laser interacting with the styryl anthracene in the dioxance,we got the one photon and two photon absorption fluorescence.We also measured the polarization ratio Ω.The experimental results point out the excited state belonging to Ag symmetry.It is one photon and two photon alowed exciting state.
