摘要：

The first-order Raman spectra of diamond anvils used in a gasketed high-pressure cell have been measured at pressure up to 250 GPa. The high-frequency edge of the Raman band, which corresponds to the Raman shift of the culet face, is represented by a function of pressure in the sample chamber up to 250 GPa. The dependence is almost independent on loading conditions. The application of the pressure dependence for pressure determination up to the multimegabars pressure region is proposed.
