摘　　要：羟基四氮茚在氯化银乳剂中的超增感作用郑均平，陈萍，张理，郑德水（中国科学院感光化学研究所，北京１００１０１）关键词羟基四氮茚，氯化银乳剂，超增感作用我们在前文中［１］报道了羟基四氮茚化合物（以下简称ＴＡＩ）对氯化银乳剂感光性能的影响，发现它不仅能提高...The sensitization of AgCl emulsion by hydroxy-tetraazaindene and the relationship between photographic properties of the emulsion and its spectral absorbance have been investigated. The results indicated that sensitivity of spectral-sensitized emulsion could be increased by hydroxy-tetraazaindene, namely, supersensitization take place, and at the same time,fog of emulsion also be inhibited. It is also found that the adding order of dye and hydroxytetraazaindene has exceedingly effect on the photographic property. By the reflection spectra and the ESR experiment, it is suggested that there is relationship between sensitivity of emulsion and the formation of aggregate of dye on the emulsion grains and the amount of light induced dye positive hole.
