Quantum Dots: Tiny Lights with Big Potential
Tiny Dots, Big Impact: A Look at Quantum Dot-Based Light Emitters For decades, LEDs have dominated the world of lighting and displays. But a new contender is emerging, promising even brighter colors, higher efficiency, and wider applications: quantum dots. These tiny semiconductor nanocrystals are changing the game with their unique ability to emit light of specific colors depending on their size. Imagine a rainbow condensed into a microscopic package. That's essentially what quantum dots are. Composed of hundreds of atoms arranged in precise clusters, these particles exhibit the fascinating phenomenon of quantum confinement. This means that electrons trapped within the dot can only exist at discrete energy levels, resulting in the emission of light at very specific wavelengths – essentially,...
