Dynamic Tuning of Quantum Dot Photoluminescence

Disclosure #: 1005
Description: The global market for quantum dot technology is expected to reach $721 million in 2013 (BCC Research). These nanomaterials can be manufactured to emit light at particular wavelengths, a property that makes them useful for displays and optoelectronic devices. However, using current technology, the wavelength of light emission from a quantum dot device is fixed once the quantum dots are manufactured. A novel material developed at the University of Nebraska—Lincoln allows quantum dot light emission to be tuned during use of a device, simply through application of moderate voltage.
Advantage(s):
  • Light emitted from quantum dots is dynamically tunable by up to 100 nm.
  • Tunable photoluminescence enhances color spectra for displays or other optoelectronic devices.
  • Simple electrical method requires only moderate bias voltages.
  • Easily manufactured from commonly available components.
  • Host matrix sustains larger electric fields than sustained by air or typical polymers.
Application(s):
  • Tunable wavelength light sources
  • Colored light sources for full color displays
  • Single-photon sources
