Abstract

Through the use of complex core-shell structures, white light emissions are observed from a single nanoparticle doped with multiple trivalent rare-earth ions. The internal structuring of the nanoparticle to allow for a controlled degree of energy transfer a common excitation wavelength yielding the white light emission is obtained. Emissions with correlated color temperatures ranging from 2700K to 5000K were produced. The stability of the phosphors to excitation wavelength variations was examined.
