In new quantum-dot LED design, researchers turn troublesome molecules to their advantage

By nestling quantum dots in an insulating egg-crate structure, researchers have demonstrated a robust new architecture for quantum-dot light-emitting devices (QD-LEDs). Quantum dots are very tiny crystals that glow with bright, rich colors when stimulated by an electric current. QD-LEDs are expected to find applications in television and computer screens, general light sources, and lasers.
