CaMgP₂O₇:Ce³⁺ Inorganic Phosphor: Three Synthesis Approaches, and Detailed Luminescence Properties

The luminescence of CaMgP 2 O 7 : x %Ce 3+ ( x = 0.1, 0.5, 1.0, 1.5, and 2.0) was synthesized and studied for their photoluminescence analysis. The phosphors were synthesized using combustion, wet chemical, and solid state reaction method and X-ray diffraction and photoluminescence analysis was performed for all samples. Analysis confirmed the solid state reaction method is the most suitable method for preparing CaMgP 2 O 7 :Ce 3+ inorganic phosphors. The excitation and emission spectra were due to d-f transitions of Ce 3+ rare-Earth ions. Further, the Strokes, Redshift, and zero phonon energy were estimated from the excitation and emission spectra. Also, the concentration quenching was observed for 1.5% doped CaMgP 2 O 7 :Ce 3+ inorganic phosphor which was due to the dipole-dipole interactions. The chromaticity coordinates obtained from Commission International de I’Eclairage diagram and corelated coordinate temperature are also discussed.
