Computational analysis on the emission of ZnO nanowires and coreshell CdSe/ZnS quantum dots deposited on different substrates

Computational analysis on the emission properties of ZnO nano wires (NWs) and coreshell quantum dots (QDs) have been made by considering the effects of scattering mechanism of the incident field and the total electric field from the surface of varied substrates. Simulation results indicate that the substrate (GaAs) having the highest emission intensity showed maximum light scattering from its surface while ITO that has the least emission intensity results in minimum rate of energy that is transferred per unit area. The simulation results proved that emission intensities spectrum is dependent on the type of substrate being used as well as the scattering of light from the surface of substrates and is independent on the type of material being deposited as well as the total electric field from the surface of substrate.
