摘　　要：发现了PbS纳米微粒对溴化银乳剂的化学增感作用,对PbS和Na2S2O3对卤化银乳剂的增感作用进行了比较,研究了增感剂用量、增感温度和pAg值、溴化银的晶型等因素的影响,以及PbS纳米微粒与HAuCl4的协同增感效应.It was found that the silver bromide emulsion can be chemically sensitized by PbS nanoparticles.Contrast experiments of PbS and Na_2S_2O_3 sensitization were carried out,and the influence of the sensitizer dosage,the sensitization temperature and pAg,the shapes of silver bromide microcrystals,and the sensitization cooperated with HAuCl_4 were studied.
