Deposition of matrix-free fullerene films with improved morphology by matrix-assisted pulsed laser evaporation (MAPLE)
Thin films of C-60 were deposited by matrix-assisted pulsed laser evaporation (MAPLE) from a frozen target of anisole with 0.67 wt% C-60. Above a fluence of 1.5 J/cm(2) the C-60 films are strongly non-uniform and are resulting from transfer of matrix-droplets containing fullerenes. At low fluence the fullerene molecules in the films are intact, the surface morphology is substantially improved and there are no measurable traces of the matrix molecules in the film. This may indicate a regime of dominant evaporation at low fluence which merges into the MAPLE regime of liquid ejection of the host matrix at higher fluence. (C) 2013 Elsevier B. V.
