Semiconductor Nanocrystals

Semiconductor nanocrystals, also known as quantum dots, are tiny particles made from semiconductor materials measuring only a few nanometers in size—thousands of times smaller than a human hair. At this scale, their electronic properties differ from bulk materials, allowing them to emit bright, tunable colors when illuminated. This makes them useful in displays, solar cells, and biological imaging. Their unique size-dependent optical and electrical behaviors stem from quantum mechanics, enabling precise control over their properties by adjusting their size, making them versatile components in advanced technology applications.
