摘要: 应用原子力显微镜对T 颗粒照相乳剂晶体表面形貌进行观察,直接测得样品的大小和厚度.得到的精细结构显示样品表面不是平坦的,而是呈现凸凹不平的结构,高低起伏最大可达5nm左右.样品经充分曝光后起伏增大到9nm左右,说明银原子簇优先在较活泼的凸起部位生成.

Abstract: The morphology of the T-grain was observed by a AFM.The size and the thickness of a crystal,and the fine morphology of the surface of the T-grain was obtained.The results showed that the surface contained a number of protrusions,which grew after a long time exposure indicating that the photolytic silver clusters,or the latent images,were formed preferentially at active positions on the surface of the grain.

Key words: AFM, photographic emulsion, T-grain, morphology
