© 2018, Allerton Press, Inc. An 18-fold increase in the mean luminescence intensity of Tb3+ 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.
