Quantum Dot Theory

Quantum Dot Theory describes how tiny semiconductor particles called quantum dots can emit light when energized. These dots are so small that their electrical properties change based on their size, leading to precise control over the color of light they produce. When energy, like electricity or sunlight, excites a quantum dot, it releases that energy as a specific color — smaller dots emit bluer light, larger dots emit redder light. This size-dependent behavior results from quantum mechanics, allowing quantum dots to be used in advanced displays, lighting, and biological imaging with high efficiency and accuracy.
