Absorption Coefficient of Alkali Halides. Part II.

Abstract

This report is the second part of the report entitled 'Absorption Coefficient of Alkali Halides.' In this second report, data analysis on the absorption coefficient in the multiphonon absorption region is carried out for LiF, NaF, NaCl, KBr, and KI. An equation is formulated to describe absorption coefficient as a function of both frequency and temperature. Constants in the equation were determined based on data fitting calculations and empirical correlations. The Urbach rule has been found to be applicable to the UV absorption edge of the transparent region; the equation derived in this study is considered to be its matching rule in the IR absorption edge.
