| Abstract: | Surface recombination is one of the important factors to influence the optical properties and device performances of nanostructured semiconductors. Zinc oxide（ ZnO） exhibits great potentials in the field of optoelectronic devices,such as solar cells and light emitting diodes,due to its excellent optical and electronic properties and physicochemical stability. This work utilized MATLAB program to solve the diffusion equations in order to theoretically simulate the surface recombination velocity of ZnO nanorods prepared by chemical bath deposition method. Combined with the experimental decay curves,the effects of surface recombination on the optical properties of ZnO nanorods had been revealed. |
