The photoluminescence (PL) spectra of high quality single phase samples of the planar polymers of C
60 have been studied as a function of pressure up to 4
GPa. The intensity distribution between the bands and their pressure-induced shifts differ among the pristine C
60, tetragonal and rhombohedral polymeric phases of C
60. The changes in the PL spectra of the planar polymers of C
60, as compared to the pristine material, are discussed in relation to the calculated electronic structure of the C
60 polymers. The obtained data can be used to effectively characterize the planar polymeric phases of C
60.
