摘要: 片状颗粒以及板状双层及多层结构晶体的出现,促使高感光度彩色胶卷的面世。T-颗粒是当今卤化银乳剂复合结构的一种很重要的类型。由于它具有一系列优点:表面/体积比值高,受光面积大,侧向散射少,染料吸附量多而越来越受到人们的关注。

关键词: T-颗粒乳剂, 制备, 颗粒分布统计

Abstract: A monodispersed tabular grain emulsion was prepared successfully by pAg-controlled double-jet methds,The functions of pBr,addition time of aqueous solutions of silver nitrate and halide,ripening time,concentration of gelatin,content of iodide and so on were investigated in this work.The results were observed that number of the hexagonal tabulargrains was 92% of the number of the whole silver halide grains and the diameter of circle corresponding to the average projected area of the tabular grains was 1.2μm and the aspectratio was 14.The results indicate that the nucleus formation and ripening stages have important function for preparing monodispersion tabular grains.

Key words: tabular grain emulsion, preparation, dispersion of grains.To whom correspondence should be addressed
