主光亮剂：苄叉丙酮、邻氯苯甲醛、对氯苄叉丙酮、洋茉莉醛、茴香醛等，起光亮、整平作用。
Main brighteners: benzylidene acetone, o-chlorobenzaldehyde, p-chlorobenzylidene acetone, jasmonaldehyde, anisaldehyde, etc., play a brightening and leveling role.
载体光亮剂：月桂醇聚氧乙烯醚、壬基酚聚氧乙烯醚、壬基酚聚氧乙烯醚磺酸盐、脂肪族聚氧乙烯醚硫酸钠等，能溶解主光亮剂、增大阴极极化、降低表面张力等作用。
Carrier brighteners: lauryl alcohol polyoxyethylene ether, nonylphenol polyoxyethylene ether, nonylphenol polyoxyethylene ether sulfonate, aliphatic polyoxyethylene ether sodium sulfate, etc., can dissolve the main brightener, increase cathodic polarization, reduce surface tension and so on.
辅助光亮剂：萘磺酸钠（NNO）、烟酸、二苯醚、肉桂酸等，能扩大光亮剂电流密度范围、提高镀液的分散能力和覆盖能力、增加极化度。
Auxiliary brighteners: sodium naphthalene sulfonate (NNO), nicotinic acid, diphenyl ether, cinnamic acid, etc., can expand the range of brightener current density, improve the dispersion and coverage ability of plating solution, and increase polarization.
溶剂：最常加入乙醇做溶剂，增加光亮剂的稳定性。
Solvent: Alcohol is most often added as solvent to increase the stability of brightener.
