Abstract
Based on the discrete dipole approximation (DDA) algorithm, the absorption spectra and near electric field of ZnO nanospheres with the radius of 10−30 nm in the infrared band were calculated. The position of absorption peak is slight blue-shift when the particle radius increases, and it is red-shift with the ambient refractive index. The near-field enhancement was calculated at the resonance wavelength, the results show that it increases with the particle radius, but it decreases with the ambient refractive index. The spatial distribution of temperature was analyzed when ZnO nanoparticle was incident by infrared light, and it was found that the maximum of temperature rising inside the particle increases with the absorption cross-section of the particle.
