چکیده
Semiconductors with dimensions in the nanometer realm are important because their electrical, optical and chemical properties can be tuned by changing the size of the particles. These nanostructures have attracted much interest due to their fundamental importance in bridging the gap between bulk matter and molecular species [199, 200]. Optical properties of nanoparticles are of great interest for application in optoelectronics, photovoltaics and biological sensing. Advances in the synthesis of highly luminescent semiconductor nanocrystals currently allow their extensive applications in different fields, ranging from optoelectronic to bio-imaging. Depending on the applications, surface modifications of semiconductor nanocrystals are essential. For example, a water soluble surface is necessary for biological labels. An electron conduc-
