摘要：

A new phosphate Ba3In4(PO4)6 has been discovered in the exploration of novel host materials for color-tunable phosphors in BaO-In2O3-P2O5 system. The crystal-structure determination using powder XRD data reveals it belongs to the cubic langbeinite structure type (S.G. P213), unlike Mg3In4(PO4)6 crystallizing the triclinic system (S.G. P1¯). The existence of PO4 has been verified by IR spectra of the title compound. DTA and experimental indicate that this new phosphate has a high melting point of ∼1293 °C. Combined with calculated electronic ...
