对光反应变色 polymolybdate 柠檬性的酸合成电影被制作。在紫外照耀以后,有器官 / 无机的部件的不同臼齿的比率的合成电影展出了不同颜色,这被发现。紫外照耀电影看了深蓝色的、黑暗的黄褐色、轻的海绿色颜色比率什么时候分别地是 1.0, 0.3 和 0.2。在紫外照耀对器官 / 无机的部件的比率敏感以后,它被 polymolybdate 种类在合成电影形成了的拉曼系列识别,因此导致照耀的电影的不同颜色。柠檬性的酸在对光反应变色过程期间起了一个重要作用。在紫外轻照耀下面,它用作压制 photogenerated 电子和洞的再结合让 polymolybdates 显示出紫外轻对光反应变色的洞 scavenger。
Photochromic polymolybdate-citric acid composite films were fabricated. It was found that after UV irradiation the composite films with different molar ratios of organic/inorganic components exhibited different colors. The UV-irradiated films showed dark blue, dark khaki and light sea green colors when the ratios were 1.0, 0.3 and 0.2, respectively. It was identified by Raman spectra that the polymolybdate species formed in the composite films after UV irradiation were sensitive to the ratios of the organic/inorganic components, thus resulting in the different colors of irradiated films. Citric acid played an important role during the photochromic process. Under UV light irradiation, it served as hole scavenger that suppresses the recombination of photogenerated electrons and holes to make the polymolybdates show UV light photochromism.
