  • Electrochromic system
    Patent number: 6861014
    Abstract: An electrochromic system having a first electrode disposed on a transparent or translucent substrate, a second electrode, an electrolyte, an electron donor in solution in the electrolyte, and a nanoporous-nanocrystalline film. The nanoporous-nanocrystalline film has a semiconducting metallic oxide with a redox chromophore adsorbed thereto, intermediate the first and second electrodes.
    Type: Grant
    Filed: April 29, 2003
    Date of Patent: March 1, 2005
    Assignee: University College Dublin
    Inventors: Donald Fitzmaurice, S. Rao Nagaraja, Rachel Cinnsealach, Brendan Enright
  • Electrochromic system
    Patent number: 6755993
    Abstract: A method for the manufacture of an electrochromic system using a nanoporus-nanocrystalline film comprising a semiconducting metallic oxide having a redox chromophore adsorbed thereto.
    Type: Grant
    Filed: April 25, 2003
    Date of Patent: June 29, 2004

  • Electrochromic system
    Patent number: 6605239
    Abstract: An electrochromic system having a first electrode disposed on a transparent or translucent substrate and a second electrode, an electrolyte, an electron donor and a nanoporous-nanocrystalline film of a semiconducting metallic oxide having a redox chromophore adsorbed thereto being intermediate the first and second electrodes. Such a system has a very rapid electrochromic effect.
