We measured refractive index of n type Hg(subscript 1-x)Cd(subscript x)Te with the null ellipsometric spectrum method over the visible light region, and the dispersion spectra with compositions x ranging from 0.2 to 0.46 have been obtained at different temperatures. The reflectivity has been calculated in the wavelength region above the absorption edge at temperatures from 77K to 300K. A peak over the visible light region appears just at the wavelength corresponding to the band-gap energy E(subscript 1)(x,T) of Hg(subscript 1-x)Cd(subscript x)Te. E(subscript 1)(x,T) can be described by an empirical formula.
