title: Direct measurement of the singlet oxygen lifetime in zeolites by near-IR phosphorescence.
abstract: Time-resolved near-IR phosphorescence spectroscopy was employed to determine the lifetime of singlet oxygen in Y-zeolites and porous silica and it was found to depend strongly on the alumina content of the zeolite.
