Colloidal Quantum Dots

Colloidal quantum dots are tiny particles, mere nanometers in size, made from semiconducting materials. They have unique optical and electrical properties that change based on their size. This size-dependent behavior allows them to emit specific colors of light, making them useful in various applications like displays, solar cells, and medical imaging. Colloidal refers to their ability to remain suspended in liquid, which simplifies their production and use. Their versatility and tunable properties make quantum dots an exciting area of research in technology and nanoscience.
