Dr. Ms. Kamiko Chang, Ph.D(University of Science and Technology Beijing, China)
Monodisperse Quantum Dots have many interesting characteristics that not only contribute to numerous applications but also display phenomena that are substantial to the fundamental study of Physics. The ability to control their shape, size, number of electrons, and coupling strength has made them particularly attractive for experimental studies. Monodisperse Quantum Dots have received great attention due to their unique tunable optical properties in sensing and optoelectronics applications. QDs are new fluorescent material widely used as probes, biological labeling, live cell imaging and many more biological applications.

Monodisperse Quantum Dots can be used in different ways to detect analytes based on the fact that fluorescence properties alter with the presence and nature of adsorbates. Fundamental studies have revealed that chemical or physical interactions between a given chemical species (the analyte) with the QDs results in the quenched fluorescence intensity.

Monodisperse Quantum Dots are nano sized semiconductor particles having their size reduced in all three dimensions; as size reduces the diameter of the particle approaches the exciton Bohr diameter and the charge carriers become confined in three dimensions. This phenomenon is known as quantum confinement, causes the continuous band of the bulk to split into discrete, quantized levels.

Monodisperse Quantum Dots can be used in different ways to detect analytes based on the fact that fluorescence properties alter with the presence and nature of adsorbates. Fundamental studies have revealed that chemical or physical interactions between a given chemical species (the analyte) with the QDs results in the quenched fluorescence intensity. Specific fluorescence quenching has been used to measure cationic concentrations, such as Cu²+fluorescence intensity decreases as concentration of Cu²+increases or for the detection of pepsin.

Size-dependent optical properties of Monodisperse Quantum Dots, broad excitation spectra , narrow, tunable and symmetric emission spectra, easily tunable band gap with size can be exploited in optoelectronics devices including LEDs, Solar Cells, Lasers etc. It was found that modulation of band gap through size offers new ways to control photo response and photo conversion efficiency of the solar cell. In solar cell sunlight excites the electron from valance band to conduction band and creates electron hole pair. Flow of electrons takes place across the p-n junction hence constitute electricity.
