On the analysis of the thermal line shift and thermal line width of ions in solids

A method of analysis for the thermally induced line shift and line width of spectral lines regarding the Raman process of ions in solids utilizing rational approximations for the Debye functions is presented. The E-2 level unsplit R-line in V2+:MgO is used as an example to illustrate the utility of the methods discussed here in providing a new analytical tool for researchers. Published by Elsevier B.V.
