Abstract:
Na3Cd4(PO4)(P2O7)2 and Na4Mg3(PO4)2(P2O7) were synthesized via a high-temperature solution. Their structures altered from disorder to order, and symmetry shifts were also documented. They exhibited the shortest cutoff edges (<190 nm) among mixed P-O anionic phosphates. Na4Mg3(PO4)2(P2O7) exhibited moderate second harmonic generation (SHG) efficiency (∼0.5 × KH2PO4 (KDP)) with phase-matching capability.
