摘要：
Elastic moduli and refractive index of diamond, in the temperature range 300-1600 K, are determined using Brillouin scattering. The elastic moduli decrease by only approximate to 8% up to 1600 K, indicating that diamond retains its reputed hardness even at high temperatures. We review the most commonly employed scattering geometries in Brillouin scattering (viz. backscattering, 90 degrees scattering, and platelet geometries), and discuss in detail the experimental errors which must be considered in each case.
