Denice D. Denton 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).

  • Making polymer thin films for optical uses
    Patent number: 5511143
    Abstract: A method is disclosed for the deposition of plasma films in which the optical index of refraction of the deposited film can be varied continuously or discontinuously as the material is deposited. The change in refractive index is accomplished by changing the input power applied to the plasma chamber. The method can be used to create optical wave guides from material of a single input monomer vapor.
    Type: Grant

  • Photovoltaic cell with photoluminescent plasma polymerized film
    Patent number: 5304255
    Abstract: Plasma polymerized organic films deposited on a substrate exhibit broad bandwidth photoluminescence after excitation with blue, violet, or ultraviolet light. The photoluminescent properties of such organic films may be exploited by using such films as wavelength transformers for photovoltaic materials, as organic solid-state gain media, as process quality control tools, and as color-correcting coatings for fluorescent lamps.
