感光乳剂中增感染料对溴化银晶形的调变作用

研究了增感染料３、３＇－二（３－磺酸丙基）－５、５＇－二苯基－９－乙基碳菁钠盐和３、３’－二（３－磺酸丙基）－１１－乙基－二苯并［ｅ，ｅ＇］噻碳菁内盐对溴化银晶体形貌变化的影响。结果表明：它们具有晶形调变作用，这种作用受染料的种类、加入量等条件影响，在一定条件下，它们对晶体生长可起促进或抑制作用。

A Crystal-Form-Modification Effect of Sensitizing Dyes on Silver Bromide in Phothographic Emulsions

The effects of sensitizing dyes sodium 3,3'-bis(3-sulfopropyl)-5,5'-diphenyl-9-ethyl-oxacarbocyanine and 3,3'- bis( 3-sulfopropyl )-11-ethyl-dibenzoe,e']thiacarbo-cyanine inner salt on the forms of silver bromide crystals were investigated.It was indicatedthat these two compounds had crystal-form-modification effects ,and it was influenced by thekinds and amount of the incorporated sensitizing dyes.Under certain condition,the sensitiz-ing dyes could enhance or inhibit the grownth of crvstals.
