光敏玻璃是熔有贵金属离子,特别是铜、银或金的玻璃。光敏玻璃经短波辐射(紫外线)曝光,贵金属离子被还原成原子。玻璃再受热,原子就聚集成较大的微粒,玻璃受辐射曝光的区域则出现可见的有色影象。光敏玻璃通过激活辐射产生的潜影只有在热处理之后才能成为可见影象。该影象在光敏玻璃中产生是基于微粒的凝聚,而不同于曝晒作用之处在于它是一个不 Photosensitive glass is a glass fused with precious metal ions, especially copper, silver or gold. Photosensitive glass by shortwave radiation (UV) exposure, precious metal ions are reduced to atoms. When the glass is heated again, the atoms gather into larger particles and the visible colored image appears in the glass exposed to the radiation. The latent image that the photosensitive glass produces through activating the radiation can become the visible image only after the heat treatment. The image is produced in a photosensitive glass based on the aggregation of particles, but differs from the exposure in that it is a
