新型偶氮化合物的光致双折射及双波长图像共存研究
Photo-Induced Birefringence and Bicolor Image Storage in Azo-Doped Polymer Film
偶氮化合物 光致双折射 四波混频 双波长共存 azo compound photo-induced birefringence degenerate four-wave mixing bicolor storage
摘要
合成了新型偶氮分子4-硝基-3-偶氮-9-乙基-咔唑(ANECz)，将其掺入聚甲基丙烯酸甲脂(PMMA)中制成薄膜器件。实验结果表明，样品具有极大的光致双折射(δn=1.8×10-2)。还利用四波混频(DFWM)技术实现了双波长光点及图像的共同存储，给出了相应的光电记录曲线和摄影记录，并分析了双波长共存中的竞争机制。
Abstract
A new type molecule [3-azo-(4′-nitro)]-(9-ethyl)-carbazole (ANECz) doped in poly (methyl methacrylate) (PMMA) was synthesized and studied. The polymer film possesses large magnitude of photo-induced birefringence (δn=1.8×10 -2 ). Bicolor image storage has been performed by degenerate four-wave mixing (DFWM) technique. The competition mechanism of bicolor storage was analyzed. Both photoelectric and image storage records were presented.
