Reaction Temperature Dependent Formations of the Zero-and One-Dimensional ZnS:Mn Nanocrystals

摘要

Low dimensional semiconductor nanocrysals have attracted considerable interest over the past few decades. These materials exhibit unique chemical and physical properties that can be applied to non-linear optics or electronic devices, and more recently to some advanced biotechno-logy areas. There has been considerable progress in the methods for preparing semiconductor nanocrystals including gas, solid, and aqueous solution phase reactions at various temperatures and pressures. In addition, recent studies have shown that the size and shapes of low dimensional nanocrystals can be tuned by controlling the reaction conditions, such as the concentration of precursor materials as well as the nucleation and crystal growth temperature.
