Quantum dots are nanoscale semiconductor physical systems in which charge carriers are confined in all three spatial dimensions, leading to discrete, atom-like energy levels and size-tunable optical and electronic properties. Their behavior is governed by quantum confinement, Coulomb interactions, and surface states, and is typically modeled using effective-mass, k·p, or tight-binding approaches. Quantum dots can be formed via colloidal synthesis, epitaxial self-assembly, or lithographic patterning, and exhibit phenomena such as single-photon emission, fluorescence intermittency, and Coulomb blockade. They serve as platforms for investigating coherent control, exciton dynamics, spin qubits, and engineered light–matter interactions in optoelectronic and quantum information devices.
Photoinduced electron/energy transfer reversible addition-fragmentation chain-transfer (PET-RAFT) polymerization enables precise light-controlled polymer growth. Traditional near-infrared strategies often rely on nonlinear ...
