James Anthony Dorman 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).

  • ADAPTIVE SOLID-STATE LUMINESCENT PHOSPHORS
    Publication number: 20240076544
    Abstract: The absorbance or emission wavelength of composite materials comprising a transition metal doped shell disposed over a rare earth doped core and a functionalizable group on the surface of the transition metal doped shell can change upon subjection to a carboxylic acid. This method of changing the absorbance or emission wavelength of a composite material can be used to identify counterfeit currency using an ink comprising a composite material.
    Type: Application
    Filed: August 10, 2023
    Publication date: March 7, 2024
    Applicant: Board of Supervisors of Louisiana State University and Agricultural and Mechanical College
    Inventor: James Anthony Dorman
