摘要: 70年代,人们对纳米粒子的“量子尺寸效应”和它的介观相特性进行了初步的研究。近20年来,这一领域得到了迅速的发展。它们的发展在很大程度上推动了照相化学的发展,对揭示照相过程中潜影银簇、显影银丝等和超细粒子有关的特殊现象的本质及机理有着不可低估的作用。

Abstract: ;Three ultrafine AgBrI emulsions were prepared with different sizes. It was observed that the ionic conductions were directly proportional to the grain size, whereas the photoelectron life times were inversely proportional to the grain size. The sensitivities and contrasts of these emulsions would be increased obviously when they were sensitized with (NH2)CSO2. The chemical sensitized effect of (NH2)CSO2 is better than sulfursensitization, goldsensitization and sulfurplusgoldsensitization.
