制备了高结晶质量、大尺寸、光学性能优异的E，E-1，4-双[4 '-（N，N-二丁基氨基）苯乙烯基]-2，5-二甲氧基苯（DBASDMB）有机晶体。比较研究了晶体的线性和非线性特性。双光子泵浦的弛豫动力学与单光子泵浦的弛豫动力学非常相似。该晶体具有很强的双光子激发荧光和放大自发辐射。高效的双光子吸收、相当高的荧光量子效率、高晶体质量以及受激发射使得有机晶体成为频率上转换和其他光电领域的理想应用。
E, E-1, 4-bis[4'-(N,N-dibutylamino)styryl]-2,5-dimethoxy-benzene (DBASDMB) organic crystals with high crystalline quality, large size and excellent optical properties are prepared. The linear and nonlinear properties in the crystal are comparatively studied. The relaxation dynamics pumped by two-photon are very similar with that pumped by one-photon. The crystal exhibits very strong two-photon excited fluorescence and amplified spontaneous emission. Efficient two-photon absorption, reasonably high fluorescent quantum efficiency, and high crystal quality together with stimulated emission make organic crystals ideal for the application in frequency upconversion and other optoelectronic fields.
