Title: Luminescence of Ce/sup 3 +/-sensitized and Tb/sup 3 +/-activated gadolinium metaphosphates (GdP/sub 3/-O/sub 9/-Ce,Tb)

Journal Article · · J. Solid State Chem.; (United States)

Energy transfer phenomena in rare-earth metaphosphate compounds have been investigated. For monoclinic GdP/sub 3/O/sub 9/-Ce,Tb (1%) at 300 K, it is shown that energy transfer does not take place from Ce/sup 3 +/ to Gd/sup 3 +/, but from Gd/sup 3 +/ to Ce/sup 3 +/. Moreover, no energy migration over the Gd/sup 3 +/ sublattice was observed. In the case of orthorhombic La/sub 1-x/Gd/sub x/P/sub 3/O/sub 9/-Ce,Tb (1%) (x less than or equal to 0.68) on the other hand, the excitation energy migrates from the Ce/sup 3 +/ ion to the Tb/sup 3 +/ traps via the Gd/sup 3 +/ sublattice. The energy migration over the Gd/sup 3 +/ ions is probably one-dimensional. In CeP/sub 3/O/sub 9/ rapid energy migration occurs over the Ce/sup 3 +/ ions.
