摘要
本文研究了多结构立方体溴化银乳剂微晶的壳层制备。在壳层制备过程中，ｐＡｇ值，ＴＡＩ和氨能明显影响晶体的生长和再成核过程，对立方体ＡｇＢｒ晶体而言，包壳速度相同时，再成核晶体数随包壳时，ｐＡｇ值的增加或ＴＡＩ的存在而增加，随着氨的存在而下降，当ＴＡＩ存在时，晶体习性由立方体转向八面体。在本实验条件下，当制备壳层的包壳速度比达到１：３．３时，乳剂的感光度有明显的增加。
The
preparation of shell layer of multistructure silver bromoiodide cubic microcrystals was studied.
During the preparation of shell layer, the pAg value TAI and ammonia affected crystal growth
and renucleation apparently. For AgBr cubes, the number of renucleated crystals was increased
with the increase of pAg value or the adding of TAI under the same reactant addition rate. The
crystal habit was transferred from cube to octahedra when TAI existed. The number of
renucleated crystals was decreased when ammonia existed.The sensitivity wasn't increased
apparently when adding rate ratio of the reactant reached 13.3 under the condition of our
experiments. But it was affected by silver quantity ratio between seed and shell. Sensitivity
was increased about 80% when the silver quantity ratio between seed and shell was increased
from 0.831 to 4.51, at the same time fog was almost unchanged.\;
