Abstract
In this paper, the Brus equation was used to study the effects of quantum confinement energy on the optical properties of material with quantum dot (QD). It was found that the wavelength and energy gap depend on the quantum confinement energy. With the increase in the energy of quantum confinement, the energy gap increases and the absorption wavelength decreases and shifts toward the UV region. This large blue shift observed in CdS and ZnSe QDs could be exploited for the potential applications as smart materials in photonic nanodevice and various other applications.
