Caption

Quantum dots (QD) are nanoscale crystals that can emit light at different wavelengths creating brilliant colors. Scientists can control the size of a QD in order to determine which color it emits. This array moves from blue emitting QD with radii of 2-3 nm up to red QD with radii of 5-6 nm. Learn more by watching episode 4 of Nanotechnology: Super Small Science.
