| 摘 要： | 本文利用紫外 可见吸收光谱、光谱曝光等手段研究了5种短波长菁染料,比较了它们在氯化银乳剂上的光谱增感作用,得出3种较好的短波长增感染料,并研究它们在氯化银颗粒上的吸附行为.结果表明,这3种染料在氯化银颗粒上均有吸附,并能有效地提高氯化银乳剂在短波长区的感光度.

| Abstract: | In this paper five short wavelength cyanine dyes have been studied with the comparison of their spectral sensitizations on silver chloride emulsions by UV Vis spectroscopy and other methods.The results show that three cyanine dyes can be adsorbed on silver grains effectively indicating these good spectral sensitization can improve the sensitivity of the silver chloride emulsion in the short wavelength. |
