Large ZnSe nanocrystals are expected to be promising blue-light emitters with an emission peak of 455–475 nm, which is important for the construction display apparatus. The final size via one-step injection can varied by reactivity Zn and Se precursors; however, it has a limit <5 nm. To describe key factors in determining nanocrystals, we proposed nuclei number-considered LaMer model based on M...
