A New Iodate-Phosphate Pb2(IO3)(PO4) Achieving Great Improvement in Birefringence Activated by (IO3)− Groups
Abstract
The first divalent-metal iodate-phosphate, Pb2(IO3)(PO4), has been prepared via the strategy of introducing (IO3)− into phosphate. The structure features a unique 3D network where [Pb(IO3)]+ ∞ and [Pb(PO4)]− ∞ layers are alternatively interconnected. The birefringence of Pb2(IO3)(PO4) is greatly increaed to 0.060 at 1064 nm.
