They are especially suitable as host lattice for luminescent materials including laser devices [ref. 3 and references therein]. Within lanthanides elements, dysprosium is known to be a good dopant and activator for different inorganic lattices.

The structure belongs to the α-Ca2P2O7 isotypical pyrophosphate series SrMP2O7 (M = Cr, Mn, Fe, Co, Ni, Cu, Zn). MgII atoms occupy square-pyramidal coordination and are isolated in the structure. [MgO5] units and the [P2O7] groups form a three-dimensional framework with channels along [100] and [010], in which are located Sr2+ ions. [on SciFinder(R)]
