Fluorescence study of trivalent americium in fluorozirconate glass

Abstract

The fluorescence spectrum of tripositive americium in a fluorozirconate glass at low temperature has been measured. Six fluorescence lines were observed between 515 to 880 nm and identified as Am3+ transitions. Fluorescence decay measurements at 15 K are reported for transitions that originate from states 5D1′ (∼1.0 ms) and 5L6′ (∼17 μs). The 5D1′ state was excited directly to produce fluorescence in order to confirm the assignment of the excited state.
