OPTICAL LIMITING AND RELATED UPCONVERTED EMISSION IN FULLERENE COMPLEX

Abstract
Optical limiting and related upconverted emission were reported in fullerene complex C60[W(CO)3diphos] in toluene solutions at various excitation wavelengths. Upconverted emission associated with the upper-lying excited states was found in both fullerene and its complex. The results indicated that C60[W(CO)3diphos] showed a good optical limiting performance in the visible spectral range.
