Semiconducting chalcogenides in various nanoforms have gained importance in recent years due to their size and shape dependent physical properties. Amongst them Cadmium Sulfide (CdS) has gained recognition as a promising material for light emitting diodes, solar cells and photoconductive devices by virtue of its photosensitive properties. So far, field emission studies on CdS nanostructures have been aimed towards the synthesis of various morphologies by a variety of routes, the attainment of lower turn on voltages, higher current densities at lower fields, and better stability.
