摘要: 通过微波对溴化银乳剂胶片的照射可以达到使感光胶片增感的目的.研究表明,短时间的微波照射就可以使溴化银胶片的感光度有明显提高,而一定时间的微波照射后,感光胶片的感光度并不象外加热方式那样出现衰退的现象.增加硫金比,微波照射后,感光度增加较多,说明感光中心与[Ag2S·Ag]+有关.并且,微波照射产生的增感效应有一定的时效性.

Abstract: It was fornd that the photographic film could be sensitized by a microwave irradiation.The film sensitivity could be enhanced greatly after a short time microwave irradiation.Unlike film heated,its sensitivity did not decrease after a long time microwave irradiation.When the S/Au ratio was raised,the film sensitivity was improved more.The reason is that the center of sensitivity is relevant to [Ag2S·Ag]+.In addition,The effect of microwave on the film sensitivity could maintain only a few hours after the microwave irradiation.

Key words: microwave irradiation, photographic sensitivity, silver halide emulsion
