Abstract
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.
