Title: Broad-emission nanocrystals and methods of making and using same

Disclosed herein are methods of preparing inorganic nanoparticles. In one aspect, the methods can comprise heating a reaction mixture comprising a C.sub.8 to C.sub.20 alkyl- or arylphosphonic acid and a source of cadmium or zinc to a temperature of greater than about 300.degree. C.; adding to the reaction mixture an injection mixture comprising a C.sub.2 to C.sub.16 trialkyl- or triarylphosphine and a source of selenium, sulfur, or tellurium; and decreasing the temperature of the reaction mixture to less than about 300.degree. C. Also disclosed herein are nanoparticles made from the disclosed methods. 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.
