A Bright Future for Quantum Dots

By Mary Page Bailey |

The novel performance characteristics and tunability of quantum dots make them a promising nanomaterial in numerous emerging applications Quantum dots (QDs) represent a broad group of semiconducting nanoparticles that feature a unique combination of optical and electronic properties. For example, QDs provide many of the same benefits as organic dyes in existing applications, but they are more robust in terms of light-conversion capabilities and can also withstand harsh chemical solvents, higher temperatures and corrosion, while generally providing a broader light-absorption band. Perhaps QDs are most prominently known for their ability to emit extremely pure colors for long durations (Figure 1) — they have been widely used to improve the display characteristics of high-end televisions. But QDs’ applicability stretches far beyond consumer electronics into wide-ranging potential end uses from solar power to agriculture to water purification. FIGURE 1.
