| 摘 要： | 利用单注法制备了平均粒径 16 5nm的卤化银乳剂 ,在此乳剂中试验了一种过增感剂Zn(Ⅱ ) -EDTA的增感作用。试验表明经过Zn(Ⅱ ) -EDTA增感的超微粒卤化银乳 ,其感光度、反差和灰雾密度等照相性能都有显著的提高。同时讨论了过增感剂的最佳加入时间、最佳用量、最佳浓度等参数 ,并且对增感作用机理作了初步的分析探讨。

| Abstract: | In this paper, silver halide emulsion with mean size of 165nm has been prepared by single-jet method, on which the effects of a kind of hypersensitizer, Zinc (II)-EDTA have been tested. Through experiments, we have gotten the results that photographic properties of ultra-micron silver halide emulsion such as sensibility, contrast, foggy, etc., all have been improved. The comparatively better use level, putting time and concentration have also been discussed.At the same time, sensitization mechanism has been discussed primarily. |
