Abstract

Temperature dependence of the photoluminescence of C₆₀ in CS₂, as a typical example of the formation of C₆₀ aggregates by the liquid-solid transition of solution, and the photoluminescence of C₆₀ in room-temperature benzene-ethanol mixtures of different compositions are presented. By comparing the photoluminescence spectra of C₆₀ in benzene-ethanol mixtures with those of C₆₀ in solution (toluene, benzene and CS₂) and C₆₀ single-crystal, it has been found that the drastic spectral change in photoluminescence spectra of C₆₀ in benzene-ethanol mixtures of different compositions are strongly ascribed to the formation of C₆₀ aggregates. Moreover, it has been found that the energy of maximum intensity and the spectral shape in the room-temperature photoluminescence of C₆₀ aggregates in benzene-ethanol mixtures are not sensitive to the ethanol volume fraction.
