Popis: The triplet excited state of C 60 ( λ max =780 nm) lives minutes and can be monitored by conventional spectrophotometers when this fullerene is incorporated inside LiY, as opposed to C 60 @HY and C 60 @MCM-41 wherein C 60 triplet lives in the submillisecond time scale. C 60 adsorbed in LiY or MCM-41 efficiently generates 1 O 2 that was detected by its characteristic NIR emission (λ em =1270 nm ) .
