Synthesis of ZnO quantum dots and their agglomeration mechanisms along with emission spectra based on ageing time and temperature |
The agglomeration mechanisms of ZnO quantum dots, from individually dispersed to coupled with number of QDs in the cluster. (a) ZnO QDs are highly dispersed; (b) the particles move irregularly in the solution and form clusters; (c) the clusters grow larger and larger; (d) hard agglomeration with strong bonds is formed. |
