Daniel Edward Shelby has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Excitation-intensity-dependent, color-tunable, dual emitting nanocrystals
    Patent number: 8410455
    Abstract: An embodiment of the invention is a device for photo-stimulated color emission having at least one plurally doped semiconducting nanoparticle comprising at least one semiconducting material and a plurality of at least one dopant coupled with an irradiation source such that the plurally doped semiconducting nanoparticle emit electromagnetic radiation at two or more wavelengths where the intensities of the emissions depend on the intensity of the irradiation. In an embodiment of the invention, the plurally doped semiconducting nanoparticle can be a doped core/shell nanoparticle where the plurality of dopants can reside in exclusively the core, exclusively the shell, or in both the core and shell.
