摘要: 本文应用微机控制的双注仪制备了碘含量为2.5%的立方体溴碘化银乳剂微晶,应用控制显影技术和电子显微镜研究了稳盐(TAI)对乳剂微晶显影中心大小和分布的影响。结果表明:TAI对S+Au增感的立方体溴碘化银乳剂微晶有明显的增感作用,而对未经化学增感的乳剂没有明显的增感作用。TAI使S+Au增感的乳剂含一个和两个显影中心的颗粒数增加。

Abstract: Cubic AgBrI microcrystals (0.25 m) were prepared by doublejet method and the distibution of development centers in the microcrystals containing stabilizer TAI was measured by arrested development and electron microscope.The results indicate that the sensitization by TAI is obvious in S+Au sensitized AgBrI cubic emulsions but the sensitivity is not changed by TAI in unsensitized emulsions. The presence of TAI increases the grain fraction of development centers containing one and twocenterpergrain class.

Key words: cubic AgBrI microcrystals, distribution of development centers, photographic properties
