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.
我们制备了具有高晶体质量、大尺寸和优异光学性能的 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。对晶体中的线性和非线性性质进行了比较研究。双光子泵浦和单光子泵浦的弛豫动力学非常相似。该晶体表现出很强的双光子激发荧光和受激放大发射。有效的双光子吸收、相当高的荧光量子效率和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应用的理想选择。
