Abstract

Another major category of nanoparticles are quantum dots (QDs), which are semiconductor nanocrystals (~2–100 nm) with unique optical and electrical properties, and widely used in biomedical imaging and the electronics industries [1‐9]. These II–VI semiconductor nanostructures (II = Zn, Cd; VI = O, S, Se, Te) display outstanding properties distinct from their bulk counterparts like broad excitation bands, large extinction coefficient, tunable emission features, bright photoluminescence, nonlinear optical properties, and high stability against photobleaching and chemicals due to the quantum nano-confinement.
