Preparation and characterization of Eu3+ ion in Mg-substituted tricalcium phosphate phosphors

Photoluminescence investigation of Eu activated Mg-substituted tricalcium phosphate (β-TCMP) phosphors were prepared by solid-state reaction. The structure and emission spectra were well characterized by X-ray diffraction (XRD) and photoluminescence (PL) techniques. The excitation and emission spectra show that all the Eu 3+ doped β-TCMP samples can effectively emit the light excited by UV light. The red-emitting β-TCMP:Eu 3+ phosphors may be efficient photoluminescent materials for solid-state lighting phosphors.
