摘要：
We have investigated variation of luminescence spectra with hydrostatic pressure up to 2.3 GPa for C-60 and C-70 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 C-60 and C-70 crystals, respectively. The estimated deformation potentials of C-60 and C-70 crystals in the low temperature frozen phase are 0.78 and 0.90 eV, respectively. (C) 2001 Elsevier Science Ltd. All rights reserved.
