Inorganic photoluminescent nanoparticles comprising a solid assembly comprising a first plurality of atoms from group II crystallized with a second plurality of atoms from group VI; at least one dimension of the assembly less than about 3.0 nm; and one or more organocarboxylate agents coupled to a surface that bounds the assembly, wherein the nanocrystal exhibits nanocrystal photoluminescence quantum yield of at least about 10%. Coupling to such surface comprises coating at least a portion of the nanocrystal being coated with the organocarboxylate agent, wherein the organocarboxylate agent is a carboxylic acid or the conjugate base of a carboxylic acid. The carboxylic acid can be is selected from formic acid, acetic acid, hexanoic acid, octanoic acid, oleic acid, and benzoic acid. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention. |
