Quantum dots are semiconductor particles a hardly any nanometres in size, having optical and electronic properties differ from larger particles due to quantum mechanics.
😊When the quantum dots are illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy.
😊Quantum dots are sometimes referred to as artificial atoms, emphasizing their singularity, having bound, discrete electronic states, like naturally occurring atoms or molecules.
😊Potential applications of quantum dots consist of single-electron transistors, solar cells, LEDs, lasers, single-photon sources, second-harmonic generation, quantum computing, cell biology research, and medical imaging.
