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.
