摘要：

Sequential irradiation with monochromatic light of 500, 480, 460, 430 nm of CdS nanocrystals (Q-CdS), whose average diameter aas 4.9 nm with the standard deviation of 2.0,, steadily narrowed the size distribution to finally give a Q-CdS colloid having an absorption spectrum characteristic of highly monodispersed Q-CdS and an absorption onset of 430 nm.
