应用可控双注仪制备了一系列碘含量相同而碘在微晶中分布不同的单分散六边形扁平淡碘化银乳剂，用扫描电镜（ＳＴＥＭ）与Ｘ－射线能谱仪（ＥＤＳ）对单个微晶进行了微区分析，并用介电损耗，微波光导等方法研究了此类乳剂微晶的结构与性能的关系。结果表明：严格控制微晶成核、成熟、生长三个阶段的条件，可制得含六边形颗粒９２％以上的扁平溴碘化银乳剂，颗粒大小变化系数小于１２％。此外碘在微晶中的分布明显影响微晶的电性质和照相性能。
A series of monodisperse hexagonal flat silver iodide emulsions with the same iodine content and different iodine distributions in the crystallites were prepared by using a controlled dual-injection instrument. The morphology of the monodisperse hexagonal flat silver iodide emulsions was characterized by scanning electron microscopy (SEM) and X-ray energy dispersive spectroscopy (EDS) The micro-area analysis of the microcrystal was carried out. The relationship between the structure and the performance of the micro-crystal was studied by means of dielectric loss and microwave light guide. The results show that the flat brominated silver iodide emulsion containing more than 92% hexagonal particles can be obtained by controlling the conditions of nucleation, maturation and growth of microcrystal. The coefficient of variation of particle size is less than 12%. In addition, the distribution of iodine in the crystallites significantly affects the electrical and photographic properties of the crystallites.
