SYNTHESIS AND OPTICAL PROPERTIES OF SEMICONDUCTOR CORE/SHELL NANOPARTICLES

The core/shell nanoparticles are a new type of material with an inner core and an outer shell made up to two different nano materials. These special types of nanoparticle heterostructure exhibit unique properties arising from the combination of core material and other shell material. The size dependent optical properties of core/shell nanoparticles have been the focus of significant result because of their absorption property, fluorescence efficiency and stability against the photooxidation. The goal of this review work is to explain the synthesis procedures and optical properties of the different types of core/shell nanoparticles.
