Quantum Dots: Tiny Particles With Big Applications

Quantum dots are nanometer-sized semiconductor particles—just a few atoms wide.
Their small size gives them unique quantum properties not seen in bulk materials.
They can emit very pure, bright colors when excited by light.
Changing their size tunes their color—smaller dots glow blue, larger ones glow red.
Quantum dots are already used in high-definition TV and display screens.
In medicine, they act as fluorescent markers to track cells and diseases.
Solar panels with quantum dots can capture sunlight more efficiently.
They’re being explored for quantum computing as potential qubits.
Quantum dots bridge nanotechnology, physics, and real-world applications.
These “artificial atoms” show how tiny particles can transform entire industries.
