对一种新型可用于可擦重写光存储的有机光致变色材料———吡咯俘精酸酐 ,测定了它的光致变色双稳态吸收光谱 ,呈色态的吸收峰在 6 35nm ,无色态的吸收峰在 385nm。利用其双稳态特性 ,在吡咯俘精酸酐 /PMMA薄膜上实现了图像光存储。所存储的图像对比度高 ,用普通相机在自然光下即可直接读出。在膜上存储的图像在室温下暗处保存 6个月未见消退 ,估计此条件下保存期可以年计。 To a new type of organic photochromic material, pyrrole fulgide, which can be used for erasable and rewritable optical storage, its photochromic bistable absorption spectrum was measured. Color absorption peak at 385nm. Using its bistable properties, image light storage was achieved on pyrrole fulgide / PMMA films. The stored image contrast is high, with ordinary camera can be directly read in natural light. Images stored on the membrane in the dark at room temperature for 6 months without regression, it is estimated that the preservation of this condition can be measured in years.
