Flux assisted synthesis of Ba9Sc2Si6O24:Eu2+ phosphor

Ba9Sc2Si6O24:Eu2+ phosphors have been reported to acquire several desired properties such as emission and excitation spectra, thermal stability, etc. needed for phosphor converted LED. Solid state reaction has invariably used prepare these phosphors. Synthesis at temperatures high 1450 °C was required in all previous studies. It is shown that use of flux can bring down the synthesis temperature 1100 °C. The so prepared had luminescence comparable with those literature.
