Disclosed herein are methods of preparing inorganic nanoparticles. In one aspect, the methods can comprise heating a reaction mixture comprising a Cto Calkyl- or arylphosphonic acid and a source of cadmium or zinc to a temperature of greater than about 300&#xb0; C.; adding to the reaction mixture an injection mixture comprising a Cto Ctrialkyl- or triarylphosphine and a source of selenium, sulfur, or tellurium; and decreasing the temperature of the reaction mixture to less than about 300&#xb0; 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.

Broad-emission nanocrystals and methods of making and using same

In one aspect, the invention relates to an inorganic nanoparticle or nanocrystal, also referred to as a quantum dot, capable of emitting white light. In a further aspect, the invention relates to an inorganic nanoparticle capable of absorbing energy from a first electromagnetic region and capable of emitting light in a second electromagnetic region, wherein the second electromagnetic region comprises an at least about 50 nm wide band of wavelengths and to methods for the preparation thereof. In further aspects, the invention relates to a frequency converter, a light emitting diode device, a modified fluorescent light source, an electroluminescent device, and an energy cascade system comprising the nanoparticle of the invention. 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.
