含雜質向列型液晶之實驗光譜

Laboratory Spectra of Doped Nematics

摘要


由於摻雜質之液晶具有超大光學非均向性與線性特質,使這類材料在廣泛的光電應用上備受矚目。在光折變向列型液晶中摻入能産生光電荷之雜質,其光導電性之增強係歸因於溶液中第三物質-即電荷轉移複合體一的生成。本論文乃就向列型液晶摻雜碳六十之可見光區吸收光譜,說明溶液中第三種物質的産生,並探討電荷轉移複合體中碳六十與液晶分子的組成比例。

並列摘要


Extraordinarily large optical anisotropy and nonlinearity have made doped liquid crystals a very attractive material for a wide spectrum of photonic applications. The enhanced photoconductivity changes observed in photorefractive nematics doped with a photocharge-generating dopant have been attributed to the formation of the third matter-charge-transfer complexes- in the solutions. This paper deals with the absorption spectra of C60-doped nematics in the visible, presents evidence of the existence of the third matter, and discusses the composition of the charge-transfer complexes.
