选取三个系列的15个染料在乳剂中作增感实验，并用摄谱仪测定了乳剂的感色峰，结果表明：吸电子取代基不利于增感，给电子取代基有利于增感；噻菁染料的加入扩大了乳剂的感色范围，弥补了卤化银乳剂在465～505nm范围内感光度的不足。

Moreover, supersensitization as well as its mechanism by stabilizers is studied in spectral-sensitized AgCl emulsion Results indicate that the adding order of stabilizer and sensitizing dye has great influence on the sensitivity of emulsion and only stabilizer added after sensitizing dye can supersensitization be obtained Apart from supersensitization and fog-inhibition by stabilizers, it is also significant to spread the amount of addition of dye, which can lead the further improvement of sensitivity of emulsion.
