Quantum dots are nano-sized semiconductor particles whose
emission color can be tuned by simply changing their dimensions.
Making the light at the end of the tunnel more efficient
Dramatic advances in the field of quantum dot light emitting
diodes (QD-LEDs) could come from recent work by the Nanotechnology and Advanced
Spectroscopy team at Los Alamos National Laboratory.
Quantum dots are nano-sized semiconductor particles whose
emission color can be tuned by simply changing their dimensions. They feature
near-unity emission quantum yields and narrow emission bands, which result in
excellent color purity. The new research aims to improve QD-LEDs by using a new
generation of engineered quantum dots tailored specifically to have reduced
wasteful charge-carrier interactions that compete with the production of light.
