二苯基戊二烯酮衍生物 非线性光学 粉末倍频系数 cinnamylidene acetophenone derivatives nonlinear optics powder second harmonic generation
摘要
制备了18种二苯基戊二烯酮衍生物的粉末晶体样品,对紫外可见光谱和光声光谱的测定表明,它们的最大紫外吸收波长λmax在320~380 nm之间,截止吸收波长λcut-of的范围为450~510 nm,在蓝光波段有良好的透光性,粉末晶体的倍频系数SHG为6~19(12ω/12ωurea),比二苯甲酮和查尔酮的衍生物的倍频性能更好,表明其在低功率激光方面的良好应用前景。
Abstract
It reports a series of new optical organic molecules of cinnamylidene acetophenone derivatives. We have synthesized eighteen compounds, and measured their powder second harmonic generation (SHG data 6~19 I2ω/I2ω urea), λ cut-off (450~510 nm) and λ max (320~380 nm). This series of molecules are found to have larger nonlinearity and shorter cut off wavelength than the chalcon derivatives. The experimental results indicate a promising application in low power lasers.
