| 摘 要： | 本文用介电损耗法测定了(NH4)2IrCl6和(NH4)3IrCl6在不同加入量(10-8～10-3M/MAgX)时对物理成熟后的AgCl(Br、I)乳剂的离子电导的影响。随着铱盐加入量的不断增大,介电吸收峰fmax不断向低频方向偏移。当掺杂量达到10-3M/MAgX时,吸收峰明显变宽。(NH4)2IrCl6和(NH4)3IrCl6的加入量相同时,这两种铱盐所导致的fmax的偏移也相近。 铱盐对于调变已经物理成熟的AgCl(Br,I)乳剂的离子电导率有很大作用。

| Abstract: | In this paper the influence of (NH4)3IrCl6 and (NH4)2JrCl6 on the ionic conductivity of AgCl (Br. I) emulsion microcrystals during the chemical ripening is studied with the aid of dielectric loss measurement in the range of 10-3-10-3M/M AgX.As the amount of iridium salts increases, the dielectric loss peak fmax shifts to lower frequency. When the amount of iridium salts added is up to 10-3M/M AgX, the dielectric loss absorption peak becomes broader obviously. When the amounts of (NH4)3IrCl6 and (NH4)JrCl6 are the same, the similar drops of fmax are observed. A probable mechanism of the phenomena observed is discussed.The addition of iridium salts has a great modifying effect on the ionic conductivity of the emulsion microcrystals during the chemical ripening. |
