About This Special Issue
Semiconductor quantum dots (QDs) exhibit diverse opto-electronic properties for multi-task applications which can be stimulated by spatial control distribution of their chemical composition. The tendency to manipulate particle size and structure of QDs have propelled nanotechnology to the forefront of different innovative research and development. The advances provide solutions to many problems with promises of almost miraculous results and achievements. A notable technique to resolve uncertainties confronting the development of solid state materials is the tunability of QDs by controlling their physical, chemical, electrical and optical properties. The unique opto-electronic properties of QDs have opened door to innovative research in solar cell, light emitting diode, biological labeling, laser and communication devices. Vying to meet the increasing demand for QDs requires a clear understanding of the surface circumscription of the surface particles which necessitates for the development of unique processing methods to enhance their optoelectronic properties at low temperature. This will circumvent risk associated with inhalation of toxic materials at high temperature synthesis as well as the blowout of synthesis vessel.
