HIGHLIGHTSMaking Smart Windows Even Smarter
October 1, 2013

Scientific Achievement

Nanocrystals of indium tin oxide (shown here in blue) embedded in a glassy matrix of niobium oxide (green) form a composite material that can switch between NIR-transmitting and NIR-blocking states with a small jolt of electricity. A synergistic interaction in the region where glassy matrix meets nanocrystal increases the potency of the electrochromic effect.

Researchers have created a thin coating of nanocrystals embedded in glass that can dynamically modify sunlight as it passes through a window.

Significance and Impact

Unlike existing technologies, the coating provides selective control over visible light and heat-producing near-infrared (NIR) light, so windows can maximize both energy savings and occupant comfort in a wide range of climates.

Research Details

  • Builds on previous advances that uses the electrochromic effect, where a small jolt of electricity switches the material between NIR-transmitting and NIR-blocking states
  • New material provides independent control over both visible and NIR light
  • Recently recognized with a 2013 R&D 100 Award and in the early stages of commercialization
