Little has been published concerning the photodynamics of PuF/sub 6/ gas, although this compound was first synthesized in 1942. The first observation of fluorescence from electronically excited PuF/sub 6/ was recently reported and its behavior was found to differ significantly from that of UF/sub 2/ or NpF/sub 6/. The photophysics of PuF/sub 6/ excited at 532 nm and at 1064 nm has now been observed in detail using laser-induced fluorescence techniques. The fluorescence emission spectra recorded are the same at both excitation wavelengths with the fluorescence intensity peaking at about 2300 nm. The fluorescence decay of PuF/sub 6/ gas excited at 532 nm was found to be laser-fluence dependent and a mechanism is proposed which accounts for this observation. Net photodecomposition of PuF/sub 6/ was rapid at a fluence of 5 J/cm/sub 2/ at 532 nm (7 ns pulse width). 33 references, 4 figures.
