Quantum Dots: Tiny Crystals With Big Applications

Quantum dots are semiconductor nanocrystals only a few nanometers wide.
Their tiny size makes quantum effects dominate their behavior.
They emit light in precise colors based on their size.
Quantum dots create ultra-vivid displays in modern TVs and monitors.
In medicine, they help tag and track cells under microscopes.
Solar cells with quantum dots can capture more of the Sun’s spectrum.
They can be tuned to absorb or emit specific wavelengths of light.
Quantum dots are studied for use in quantum computing and encryption.
Their stability and brightness outshine many traditional dyes.
They show how nanophysics turns the very small into powerful technology.
