Abstract
Photoluminescences (PL) and electrical conductivities of evaporated C70 films prepared at various substrate temperatures are studied. In C70 films prepared at low substrate temperatures, a PL peak at 1.79 eV are strongly observed, besides several peaks at 1.55, 1.67, 1.71 eV observed in the films deposited at high substrate temperatures. Thermal annealing of the films prepared at low substrate temperatures turns into the characteristic of the spectra prepared at high substrate temperatures. A novel memory effect of highly conductive state in fullerene films of C60 and C70, which is attained by a treatment of high electric fields at high substrate temperatures is also mentioned.
