超增感剂的几何位置对超增感过程的影响

本文通过溴化银单晶上的超增感体系的Dember效应测试以及相应实用乳剂体系的研究,观察到超增感作用与体系的Dember效应之间存在平行关系,并以此探讨了超增感荆发挥最佳作用时在溴化银面上增感染料与超增感剂的相对排列位置,实验结果表明,在所研究的超增感体系中超增感剂与溴化银直接接触时超增感作用最为有效。

INFLUENCE ON SUPERSENSITIZATION FOR GEOMETRIC POSITION OF SUPERSENSITIZER

The supersensitization of the supersensitizing systems based on AgBr single-crystal has been studied by means of the Dember effect.It can be considered that the role of supersensitizers can be correlated directly with their measured Dember effects.The electronic energy levels and geometric position of supersensitizer relative to those of AgBr and sensitizing dyes and the diffusion direction of the free charge carriers have been discussed.The results of the experiments showed that supersensitization will be the most efficiant in the studied supersensitizing systems when the supersensitizer is in direct contact with silver bromide.
