Abstract
A method for preparing semiconductor nanocrystals comprises reacting cation precursors and anion precursors in a reaction mixture including one or more acids, one or more phenol compounds, and a solvent to produce semiconductor nanocrystals having a predetermined composition. A method for forming a coating on at least a portion of a population of semiconductor nanocrystals is also disclosed. The method comprises forming a first mixture including a population of semiconductor nanocrystals, one or more amine compounds, and a first solvent; adding cation precursors and anion precursors to the first mixture at a temperature sufficient for growing a semiconductor material on at least a portion of an outer surface of at least a portion of the population of semiconductor nanocrystals; and initiating addition of one or more acids to the first mixture after addition of the cation and anion precursors is initiated. Semiconductor nanocrystals and populations thereof are also disclosed.
