TLDR
In this article, the authors search, compile, and analyze refractive index data for silicon and germanium and generate recommended values for the transparent spectral region were generated in the ranges 1.2 to 14 μm and 100-740 K for silicon, and 1.9 to 16 µm and100-550 K for germanIUM.Abstract:
Refractive index data for silicon and germanium were searched, compiled, and analyzed. Recommended values of refractive index for the transparent spectral region were generated in the ranges 1.2 to 14 μm and 100–740 K for silicon, and 1.9 to 16 μm and 100–550 K for germanium. Generation of these values was based on a dispersion equation which best fits selected data sets covering wide temperature and wavelength ranges. Temperature derivative of refractive index was simply calculated from the first derivative of the equation with respect to temperature. The results are in concordance with the existing dn/dT data.read more

Hamaker constants of inorganic materials
TL;DR: In this paper, a review of the applicability of the N-P representation for the analysis of the lifshitz Hamaker constants in the ultraviolet spectral region is presented. But the authors do not consider the non-retarded Hamaker constant for water, which is not true for all materials, e.g. water.
