Abstract
Elastic moduli and refractive index of diamond, in the temperature ran ge 300-1600 K, are determined using Brillouin scattering. The elastic moduli decrease by only approximate to 8% up to 1600 K, indicating tha t diamond retains its reputed hardness even at high temperatures. We r eview the most commonly employed scattering geometries in Brillouin sc attering (viz. backscattering, 90 degrees scattering, and platelet geo metries), and discuss in detail the experimental errors which must be considered in each case.
