The process of tabular crystal formation during physical ripening of fine AgX (X=Br,I) emulsions is investigated. The tabular crystal growth is realized simultaneously via two mechanisms: ionic and coalescent. The relative contribution of those mechanisms to the tabular crystal growth is determined by the conditions of the physical ripening. It is possible to control the size and shape uniformity of the final AgX tabular crystals by adjusting the relative contributions of these mechanisms.
研究了细颗粒AgX(X = Br,I)乳剂物理成熟过程中片状晶体的形成过程。片状晶体的生长通过离子和聚结两种机制同时实现。这些机制对片状晶体生长的相对贡献由物理成熟条件决定。通过调节这些机制的相对贡献,可以控制最终AgX片状晶体的尺寸和形状均匀性。
