Quantum dots are nanoscale semiconductor particles that exhibit unique optical and electronic properties due to their size-dependent quantum confinement effects. These tiny crystals, typically ranging from 2 to 10 nanometers in diameter, are composed of elements from groups II-VI, III-V, or IV-VI of the periodic table. The most common materials used for quantum dots include cadmium se... https://articlescad.com/quantum-dots-revolutionizing-technology-from-displays-to-medicine-with-nanoscale-precision-5163.html
