Effect of Photochemical and Photophysical Processes with the Participation of Oxygen on the Luminescent Properties of a Film of a Terbium(III) β-Diketonate Complex

An 18-fold increase in the mean luminescence intensity of Tb 3+ ions in a vitrified film of a terbium( III) β-diketonate complex under UV laser radiation in atmospheric oxygen at 300 K was observed. Luminescence and Raman spectroscopy data reveal that the observed effect was caused by photophysical...

Zusammenfassung:	An 18-fold increase in the mean luminescence intensity of Tb 3+ ions in a vitrified film of a terbium( III) β-diketonate complex under UV laser radiation in atmospheric oxygen at 300 K was observed. Luminescence and Raman spectroscopy data reveal that the observed effect was caused by photophysical and photochemical processes changing the geometry and structure of the complex.
