摘要: 本文制备了一种内部增感的核壳乳剂,其核经增感到一定程度后,表面形成堆积银原子作为空隙陷阱。该乳剂与表敏乳剂混合后,可提高感光度、反差和最大密度,本文研究了内增感乳剂制备过程影响因素,并对混合体系作用机理进行了初步探讨。

Abstract: Internally sensitized core-shell emulsions were prepared and it was shown that smallsilver specks formed on the surface of the core emulsion behave like hole traps.Whenthese emulsions were mixed with surface-sensitized emulsions, the sensitivity,contrast and maximum density increased.In this paper,the influence of some factors on the preparation process are studied and the function of the internally sensitized emulsions in the systermare discussed.

Key words: core-shell emulsion, sensitization, hole trap
