When PuF/sub 6/ is photoexcited at 797.3 nm, fluorescence is observed from the 1 ..mu..m electronic energy level. The lifetime tau of the fluorescence signal varies with pressure. The lifetimes cover a range of 655 to 243 ns for a pressure range of 0.5 to 72 Torr. A linear Stern--Volmer relationship was obtained over the complete pressure range considered. An extrapolation to zero pressure yields an intercept of tau/sub 0/ = 663 ns and a slope of 3.62 x 10/sup 4/ Torr/sup -1/ s/sup -1/. Fluorescence and excitation spectra are reported and are in good agreement with the previously reported absorption spectrum of PuF/sub 6/.
