研究目的
Investigating the luminescent properties and structural characterization of Ce3+ ion-doped Ba6Ca3YAlSi6O24 phosphors with a charge-compensating Na+ ion.
研究成果
Ba6Ca3YAlSi6O24:Ce3+, Na+ phosphors were successfully prepared and characterized. The study identified single and double luminescent centers and tuned the composition for optimized luminescent properties.
研究不足
The study focuses on the luminescent properties and structural characterization of specific phosphors, with potential limitations in the generalizability to other phosphor materials.
1：Experimental Design and Method Selection
The phosphors were prepared using a solid-state reaction at high temperature under a reducing environment. The phase identification was established using X-ray powder diffraction.
2：Sample Selection and Data Sources
Appropriate stoichiometric amounts of BaCO3, CaCO3, Y2O3, Al2O3, SiO2, CeO2, and Na2CO3 were mixed and heated.
3：List of Experimental Equipment and Materials
High-temperature tube furnace, Shimadzu XRD-6000 powder diffractometer, synchrotron X-ray powder diffraction at PLS-II 6D UNIST-PAL beamline, spectrofluorometers.
4：Experimental Procedures and Operational Workflow
Mixing of stoichiometric amounts of materials, heating at 950 and 1200 °C for 6 h under 8%H2/92%Ar atmosphere, phase identification, and luminescence measurement.
5：Data Analysis Methods
Rietveld refinement for structural characterization, Gaussian deconvolution for emission spectra analysis.
