Abstract

Photoupconverted emission and wavelength-dependent optical limiting and non linearity have been reported in fullerene C₆₀ and its complex C₆₀[W(CO)₃diphos] toluene solutions and sol gel films. Up converted emission indicates the absorption and emission from upper-lying excited states. Significant improvement of optical limiting performance in C₆₀[W(CO)₃diphos] compared to C₆₀ has been achieved in a wide spectral range. Optical non linearity increases with the increment of wavelength.
