Abstract
How indices of refraction n(ω) of insulating solids are affected by the volume dilution of an optical entity and the mixing of different, noninteracting simple solid components was examined on the basis of the dielectric function ε1(ω) + iε2(ω). For closely related insulating solids with an identical composition and the formula unit volume V, the relation [ε1(ω) − 1]V = constant was found by combining the relation ε2(ω)V = constant with the Kramers−Kronig relation. This relation becomes [n2(ω) − 1]V = constant for the index of refraction n(ω) determined for the incident light with energy less than the band gap (i.e., ℏω < Eg). For a narrow range of change in the formula unit volume, the latter relation is well approximated by a linear relation between n and 1/V.Keywords
