Semiconductor Quantum Dots

One of the more exciting classes of nanomaterials is semiconductor quantum dots. Due to quantum confinement effects associated with their nanoscale size and structure, amazing optical properties are obtainable for materials absorbing and emitting light from the UV to the NIR. In Chapter 4, quantum dots are discussed. A physical basis of the quantum confinement effect is described, which is then used to explain the unique optical properties these materials exhibit. Applications of quantum dots are also described in detail.
