Enhanced photoluminescence property of CaB2O4:Eu3+ phosphor prepared by calcining the Ca4B10O19·7H2O:Eu3+ precursor

The CaB2O4:Eu3+(A-900) phosphor which was obtained by calcining the Ca4B10O19·7H2O:Eu3+ precursor exhibits better dispersion and much stronger PL intensity than the CaB2O4:Eu3+(B-900) phosphor prepared by conventional solid state reaction method.
