Abstract:
1. A method for synthesizing colloidal nanocrystals of periodic table groups IV–VI compounds with a size-tunable electromagnetic emission, comprising the steps of: a) forming a first solution by dissolving a compound containing a metal selected from group IV of the periodic table in a first effective solvent; b) forming a second solution by dissolving a compound containing an element selected from group VI of the periodic table in a second effective solvent and mixing said second solution with said first solution to form a third solution; c) agitating the third solution for a selected period of time under controlled heating to grow colloidal nanoparticles of a IV–VI compound of selected mean size, said effective solvent including ligands that stabilize said colloidal nanoparticles; and d) isolating the colloidal nanoparticles of selected mean size.
