Eu2+, Ca6BaP4O17, emission color shift

https://doi.org/10.36463/idw.2020.0350

We successfully obtained Eu2+-activated Ca6BaP4O17 phosphors via the solid state reaction. With increasing the content of the Eu2+ ion, the emission peak shift from 550 nm to 610 nm. The Rietveld refinement shows that the Eu2+ ion preferentially occupies CaO7 and CaO8 sites in the host.
