Abstract:
Data in the literature on the optical properties of aluminum in the range of 198–1173 K are analyzed. Analytical expressions describing the dependences of aluminum permittivity on photon energy and temperature are proposed and tested. The spectral dependences of the aluminum absorption coefficient and specular reflectance at normal incidence, as well as of the absorption-efficiency coefficients of aluminum nanoparticles in a lithium-fluoride matrix, are calculated at different temperatures. The results obtained indicate the appearance of unusual nonlinear absorption effects in nanocomposites containing aluminum nanoparticles, which manifest themselves in a decrease in the absorption efficiency with increasing temperature at photon energies exceeding 1.40 eV.
