| 摘 要： | 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635nm，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。

| Abstract: | Pyrryl fulgide is a new type of organic photochromic material which can be used in EDRAW (Erase Direct Read After Write) optical memory. The absorption spectra of the bistability of the pyrryl fulgide are measured. The maximum absorption of the colored state is centered at 635 nm,the peak absorption of the bleached state is at 385nm. With the thermal stable states, optical images are steadily recorded on the pyrryl fulgide/PMMA film. The contrast of the recorded images is high enough, so it can be easily read out directly by a usual camera. The images on the film have been kept for six months without any degeneration. The storage period is estimated to be as years in dark at room temperature. |
