Abstract
We have investigated variation of luminescence spectra with hydrostatic pressure up to 2.3 GPa for C60 and C70 crystals in the frozen phase at 77 K. Red shifts of luminescence peaks are observed for both crystals, and the pressure coefficients are obtained to be −0.059 and −0.070 eV/GPa for C60 and C70 crystals, respectively. The estimated deformation potentials of C60 and C70 crystals in the low temperature frozen phase are 0.78 and 0.90 eV, respectively.
