Evolution of the transmission spectra of CuBr microcrystals with an average diameter of 1320 Å under high pressures at room temperature. The structure at each phase, (a) zinc blende (ZB), (b) tetragonal and (c) NaCl structure, and the corresponding spectra are shown together. The pressures were monitored by the energy shift of the R1 fluorescence line of ruby chips in the cell. |
