| 摘 要： | 利用微波吸收介电谱检测技术,测量了不同染料吸附条件下立方体氯化银乳剂的自由光电子衰减曲线,发现增感乳剂比未增感乳剂的自由光电子衰减变快,这是由于染料吸附增加了氯化银中的Agi+.对于增感乳剂,自由光电子衰减越快,说明染料吸附效果越好,相应的增感效果也就越佳.通过分析自由光电子衰减时间和寿命随染料吸附浓度和时间的变化关系,确定出了感绿染料增感立方体氯化银乳剂的最佳吸附质量比和时间的组合为8/40 000和10 min.

| Abstract: | The free photoelectron decay curves of cubic silver chloride emulsion with different dye adsorption conditions are measured by microwave absorption and dielectric spectrum detection technology.It is found that the photoelectron decay of sensitized emulsion is faster than that of unsensitized emulsion.The reason is that interstitial silver ions are increased by dye adsorption.For the sensitized emulsion,the faster of photoelectron decay indicates that the more effective of dye adsorption,and the correspondin... |
