摘要： PURPOSE:To obtain a light recording material capable of repeating regeneration and erasion, by irradiating the surface of a Ge-S type glass containing a specified proportion of Ge, and silver with light in order to deposit a thin metallic film onto the surface, and fixing the light-irradiated image on the irradiated part. CONSTITUTION:A glass plate containing 17-30atomic %, and silver in addition is sealed in a transparent sealed tube evacuated to mm.Hg, for example, so as to give Ge22S45Ag33, melted in a melting furnace heated to 800-1,000 deg.C for about 8hr and stirred. A block of glass quenched in water is taken out, sliced to about 3mm. width, the surface is mirror polished, and a plate 5 for use in image irradiation is thus obtained. The plate 5 is exposed to light emitted from a high-pressure mercury arc lamp, converged with a lens system 2, and passed through a thermal ray cut filter 3 and, for example, a circular mask pattern 4 to form the silver image 2 of the pattern 4 on the surface 1 of the plate 5 as shown in the figure. When the image 2 is irradiated with the light more intense than said light, the silver diffuses into the inner part of the glass and disappears. When the plate 5 is covered with 50-30nm thick gold or the like, the image 2 is fixed so as not to disappear. Since the thickness of silver of the image 2 is about 300nm, the plate 5 can be reused by polishing and removing it.

摘要： PURPOSE:To form metallic film on a light irradiated surface as well as an irraidated image of metallic silver and to fix the irradiated image by adding silver to Ge-S glass contg. a specified atomic percentage of Ge and by irradiating the silver added glass with light. CONSTITUTION:The basic composition of glass contg. silver consists of, by atom, (a) 12-30% As, 25-45% S and 30-50% Ag or (b) 17-30% Ge, 45-55% S and 25-35% Ag. The glass is directly vapor-deposited on a desired substrate to form a thin film. It is preferable to subject the film surface to mirror polishing. To form an image pattern on such a glass surface the surface is irradiated with light having shorter wavelengths than the proper absorption edge of the glass through a mask having the desired image pattern. The lower limit of the wavelengths is 200nm. The resulting image pattern can be erased with heat or light.

摘要： PURPOSE:To fix an irradiated image of high contrast by irradiating a chalogenide glass sheet contg. much silver with light to deposit an irradiated image of metallic silver particles on the sheet surface and forming a metallic film. CONSTITUTION:A glassy thin Ge-S-Ag film contg. 25-35atomic% Ag is irradiated with light to deposit an irradiated image of metallic particles on the film surface, and metallic silver is fixed to the film surface having the deposited irradiated image. For example, glass consisting of 17-30% Ge, 45-55% S and 25-35% Ag is cut into a sheet and irradiated with light having shorter wavelengths than the characteristic absorption edge of the glass through a mask having the desired image or pattern. Within several sec after the irradiation, the irradiated region begins to whiten, and usually after 5min a white image or pattern of high contrast is obtd. When the image is required to be fixed, the image or pattern of the substrate glass is coated with Au, Ni or the like by vacuum deposition or other method in 50- 300Angstrom thickness.
摘要翻译：目的：通过照射chalogenide玻璃板来限制高对比度的照射图像。大量的银用光将金属银颗粒的照射图像沉积在片材表面上并形成金属膜。构成：玻璃薄的Ge-S-Ag薄膜用光照射25-35原子％Ag以在膜表面沉积金属颗粒的照射图像，并将金属银固定到具有沉积的照射图像的膜表面。例如，将由17-30％Ge，45-55％S和25-35％Ag组成的玻璃切割成片材，并通过具有所需图像的掩模用比玻璃的特征吸收边缘波长短的光照射或图案。在照射后几秒钟内，照射区域开始变白，通常在5分钟后，白色图像或高对比度图案被显示。当需要固定图像时，通过真空沉积或其他厚度为50-300埃的方法，用Au，Ni等涂覆基板玻璃的图像或图案。
