Quantum dots, which are nanoscale semiconductor crystals, are a key area of focus within nanotechnology due to their unique size-dependent optical and electronic properties. These properties, particularly the ability to tune light emission and absorption based on size, have led to applications in diverse fields like medicine, displays, and solar cells. Here's a more detailed look: What are Quantum Dots? • Quantum dots (QDs) are semiconductor nanocrystals, typically ranging from 2 to 10 nanometer
