The significance of surface states in nano-structures is studied using CdS nanoparticles. Spectral features like peak red-shift due to organic capping and influence of surface states have been observed. The pronounced enhancement of emission from surface states can be dominant with certain modiciation of CdS nanoparticles. Spectral behaviors of electroluminescence in different temperature are also studied.
