| 摘 要： | 本文对两种阴阳离子菁染料在碘溴化银立方体颗粒表面的聚集行为进行了研究。用紫外-可见分光光度计测定了菁染料J-聚集的反射光谱曲线。与对应的阴离子、阳离子菁染料各自在碘溴化银立方体颗粒表面的聚集进行了实验对比。结果表明:阴阳离子菁染料吸附在碘溴化银立方体颗料表面形成的J-聚集态的反射光谱具有单个阴离子、阳离子菁染料形成J-聚体反射光谱的峰值波长。表明阴阳离子菁染料具有两个感色区域,既有阴离子菁染料的感色区又有阳离子菁染料的感色区。 |

| Abstract: | Spectral sensitivity is a key technology of modern photography. Because J-aggregates of cyanine dye exhibit sharp absorption bands (i. e. , J-band), they are important sensitizers. In this article, the J-aggregation behavior of two kinds of anionic-cationic cyanine dyes adsorbed on the AgBrI cubic microcrystals was studied. The reflectance spectral curves of J-aggregating dyes were measured by UV-Vis. spectrophotometer, and were compared with the J-aggregation of anionic and cationic cyanine dyes. The results show that the reflectance spectra of J-aggregates of anionic-cationic cyanine dyes adsorbed on AgBrI microcrystals have peak wavelengths of anionic and cationic cyanine dyes. Anionic-cationic cyanine dyes have two sensitivity regions, including both the sensitivity region of anionic cyanine dye and the sensitivity region of cationic cyanine dye. |
