Paper Abstract

On the basis of size effect models of aluminum oxide particle optical constant, this paper introduces temperature amendment of complex refractive index below melting point using the relationship between complex refractive index and temperature; while the amendment is introduced above melting point using the relationship between oscillator density and quality density. To found the dependence of complex refractive index of aluminum oxide particle on varying with diameter, then calculate it at the wavelength of 0.6328μm and the temperature ranged from 300K to 3000K. Through comparing with experimental value of complex refractive index for bulk aluminum oxide, the response of optical constant to temperature is obtained. It is concluded that the evolution of complex refractive index of aluminum oxide particles with temperature is basic in agreement with the bulk aluminum oxide, and showing obvious size effect of complex refraction index of particles within 1.3<χ <7.4. Finally, the index of complex refraction of aluminum oxide particles with the diameter of 0.97μm is calculated from 300K to 3000K, which further validates the size effect.
