The size-distribution of ZnS nanoparticles (Q-ZnS) of 4.2 ± 0.6 nm was narrowed to 2.6 ± 0.2 nm by sequential irradiation with monochromatic light of 313 nm, 303 nm, and 297 nm to an air-saturated ZnS colloidal solution in the presence of sodium hexametaphosphate as a stabilizer and methylviologen as an electron acceptor.
ZnS纳米颗粒(Q-ZnS)的尺寸分布从4.2 ± 0.6 nm缩小至2.6 ± 0.2 nm,方法是对空气饱和的ZnS胶体溶液进行313 nm、303 nm和297 nm的单色光依次照射,并在
六偏磷酸钠作为稳定剂和
甲基紫罗兰作为电子受体的存在下进行。
