摘要/Abstract

摘要： 研究了甲酸盐掺杂和草酸盐掺杂对AgBr乳剂和亲水型PTG材料感光性能的影响.实验结果表明,掺杂后的AgBr乳剂在PTG材料中作为光敏元显著提高了其相对感光度,而不引起灰雾的增加;掺杂增感与硫增感、金增感、硫加金增感在PTG材料中同样表现出协同增感效果,使PTG材料的感光度得到进一步的提高;掺杂后的AgBr乳剂在PTG材料中具有一个最佳使用量,即Ag-Br与硬脂酸银的摩尔比为1:4.

Abstract: The effect of formate and oxalate dope on the photographic properties of AgBr emulsion and water-base photothermographic materials was respectively studied in this paper.The results showed that the relative sensitivities of PTG materials were remarkably increased when the doped AgBr emulsions were used as silver elements in PTG materials,whereas the fog did not change. In additon,dope sensitization also cooperated with sulfur,gold,sulfur plus gold sensitization in PTG materials,which further improved the relative sensitivity of PTG materials.Doped AgBr emulsion had an optimal amount with AgBr to silver stearate of 1:4 in PTG materials.

Key words: photothermographic materials, dope, carboxylate, chemical sensitization
