Popis: |
Photoluminescence (PL) spectra were measured on the C 60 polymeric phase prepared from a single crystal and from a microcrystalline powder treated at pressures to 15 kbar and temperatures to 600 K. It was found that the high-pressure treatment resulted in a shift of the spectral intensity distribution to lower energies compared to the well-known spectrum of pristine C 60 . A set of new lines was observed. The PL spectrum of the high-pressure phase exhibited a distinct structure contrary to that of photopolymerized C 60 . The PL intensity of the high-pressure phase showed a non-monotomic temperature dependence with a slight minimumum around 150 K. |
