Abstract

The molar absorption coefficients of spherical InP, ZnS, and InP(core)/ZnS(shell) nanoparticles have been calculated from the complex permittivities of the corresponding bulk semiconductors. The results are valid in the short-wavelength region of the absorption spectrum, where the quantum size effect is insignificant. For the imaginary part of the polarizability of core/shell nanoparticles, a formula has been obtained that is convenient for calculations in real numbers
