A comparative study of singlet-oxygen generation by С60 and С70 fullerenes

详细

The results of comparative investigations of singlet-oxygen generation by С₆₀ and С₇₀ fullerenes in tetrachloromethane solutions, aqueous suspensions, and solid-phase powders of fullerenes optically excited by cw diode arrays with different wavelengths and by pulsed xenon lamps with a band filter are presented. The measurements were performed by recording singlet-oxygen phosphorescence at the O²(¹Δ_g)–O₂(³Σ_g) transition (λ = 1270 nm).
