一、引言随着激光技术的发展,无论在激光信息处理或激光器的研制中,都迫切希望发展能实时显示并能记录、操作简单的信息记录材料。光色材料虽能实时显示,分辨率也很高,但长期保存图象有困难,而且灵敏度也比较低。光导热塑料虽然有高的灵敏度,能长期保存图象,并能近似于实时显示,但需充电、加热等,操作使用不方便;同时,由于生成的图象是霜面象,直观观察困难。自由基片是在50年代末期发展起来的一种有机非卤化银感光材料,它是基于感光层在光作用下能产生自由基,而自由基
I. INTRODUCTION With the development of laser technology, no matter in the development of laser information processing or laser, it is urgent to develop the information recording material which can display real time and can be recorded and operated simply. Light color material can be real-time display, resolution is also high, but the long-term preservation of the image is difficult, and the sensitivity is relatively low. Although the thermal plastic has high sensitivity, long-term preservation of images and can be similar to the real-time display, but the need for charging, heating, etc., inconvenient to use; the same time, the resulting image is frost-like, visual observation difficult. Free radical is developed in the late 1950s as an organic non-silver halide photographic materials, it is based on the photosensitive layer can produce free radicals under the action of light, and free radicals
