Abstract: A method for preparing semiconductor nanocrystals includes adding a non-protonated surface modification agent to semiconductor nanocrystal cores in a liquid medium to form a mixture; adding one or more precursors for forming a shell including a semiconductor material to the mixture under conditions for forming the shell over at least a portion of an outer surface of the cores, and adding an acid ligand to the mixture after addition of at least a portion of the one or more precursors. Semiconductor nanocrystals, other methods of making semiconductor nanocrystals, compositions and products including semiconductor nanocrystals are also disclosed.
