Photoluminescence Quantum Dots states and confinement of their excitons may shift their optical absorption and emission energies. Such effects are important for tuning their luminescence stimulated by photons (photoluminescence) or electric field (electroluminescence). In this article, decoupling of quantum effects on excitation and emission are described, along with the use of quantum dots as sensitizers in phosphors. In addition, we reviewed the multimodal applications of quantum dots, including in electroluminescence device, solar cell and biological imaging.

Photoluminescence Quantum Dots exhibits solid-solid phase transition like bulk semiconductors, and these transitions have a substantial influence on the optical properties of Qdots. Phase transitions in bulk materials can be induced by varying pressure, temperature and composition. Bulk CdSe may exhibit either a hexagonal wurtzite or a rock salt cubic structure with a direct or indirect band-gap, respectively. Above a pressure of ~ 3 GPa, the CdSe bulk semiconductor can be converted reversibly from low pressure wurtzite to the high pressure rock salt structures.

Doping in Photoluminescence Quantum Dots is an important aspect when Photoluminescence Quantum Dots are used for various technological applications, especially, optoelectronic, magnetic, biological and spintronic applications. These impurities, called activators, perturb the band structures by creating local quantum states that lies within the bandgaps. In the Qdots, the dopants are found to be auto-ionized without thermal activation due to quantum confinement.

Due to the high surface-to-volume ratio of Photoluminescence Quantum Dots, electronic quantum states associated with the surface (called surface states) have significant effects on the optical properties of Qdots. For example, roughly 15% of the atoms in a 5 nm CdS Qdot are at the surface. Such a high surface-to-volume ratio may allow an enhanced or reduced transfer rate of photogenerated charge carriers due to the high density of surface sites.

Due to the benefits of Photoluminescence Quantum Dots size-tunable physical properties, nanoscale semiconductor materials have promising future applications, including the optoelectronic devices such as light-emitting diodes and nextgeneration quantum dot solar cells. Moreover, nanoscale semiconductors functionalized with biomolecules are used as molecular fluorescent probes in biological applications.
