本文研究了在氯溴化银上不同类型染料的吸附和不同氯离子含量的溴化银乳剂中染料的增感作用。证明在溴化银乳剂中加入氯离子以后,光谱增感的倍率增加了。不同类型的染料呈现出不同的增感规律。份菁染料在氯溴化银乳剂上具有最好的吸附能力和光谱增感作用。实验结果还表明,染料的吸附与乳剂光谱增感效果,有着良好的对应关系。证实了染料和卤化银所形成的吸附络合物是具有照相活性的。对不同类型染料的增感现象进行了讨论。
In this paper, the sensitization of dyes in silver bromide emulsions with different types of dyes on silver chlorobromide and different chloride contents was studied. It is demonstrated that after the chloride ion is added to the silver bromide emulsion, the magnification of spectral sensitization increases. Different types of dyes show different sensitivities. Cyanine dyes have the best adsorption and spectral sensitization on silver chlorobromide emulsions. The experimental results also show that the dye adsorption and emulsion spectral sensitization effect, has a good correspondence. It was confirmed that the adsorption complexes formed by the dye and the silver halide are photographic active. The sensitization of different types of dyes is discussed.
