摘　　要：研究了把经传统化学增感即硫增感、金增感、S+Au增感、二甲氨基硼烷(DMAB)还原增感的AgBr乳剂引入光敏热成像(PTG)体系后对PTG材料感光性能的影响。结果表明,AgBr乳剂经传统化学增感后感光度均大幅增加,其中经S+Au增感后感光度可较未增感的提高6倍,将增感后的AgBr乳剂作为PTG体系的光敏元,PTG材料在感光度增加的同时灰雾并没有明显地增加。以S+Au增感和还原增感的效果为最佳,感光度可增加4倍。The influence of traditional sensitizations,i.e.sulfur sensitization,gold sensitization,sulfur-plus-gold sensitization and reduction sensitization,on the photographic properties of photothermographic（PTG） materials were studied.The results showed that the sensitivities have been improved significantly in system of silver bromide,which can be increased around six times than that of the un-sensitiezed silver bromide.The sensitivity of PTG materials have been increased about four times while the photo element of silver bromide was sensitized traditionally,but its fog level was not increased significantally.
