N2 - Based on optical scattering theory of Aden-Kerker method, the extinction efficiencies of submicron hollow particles with 5 kinds of materials, such as graphite(C), brass powder (Cu), cupric oxide (CuO), cuprous oxide(Cu2O) and soot are given in this paper. Some influences of different materials, inner radius (x), outer radius (y), shell thickness (z) and x-z ratio(x/z) on the extinction efficiencies are studied respectively. Owing to lack of literature data, the optical constants of C, Cu, CuO, and Cu2O are firstly obtained by measuring infrared spectral transmittance of material piece and retrieving the equivalent optical constants combined with electromagnetic scattering theory and K-K relation. The results show that particle C, Cu, Cu2O and Soot have a good performance in stability of extinction efficiency distribution within 3-5μm; the extinction efficiencies of C, Cu, Soot decrease gradually with the shortening of the wavelength within 3-5μm; the extinction efficiency of all kinds of particles increase along with outer radius y increased when shell thickness z is fixed.
