研究目的
Investigating the potential of dysprosium activated strontium aluminate phosphors for white LED applications.
研究成果
The synthesized SrAl2O4:xDy3+ phosphors emitted blue, yellow, and red under UV excitation, confirming their suitability for white light emission. The SrAl2O4:0.3 Dy3+ phosphor is identified as a more suitable phosphor for white light source applications.
研究不足
The study is limited to the synthesis and characterization of dysprosium activated strontium aluminate phosphors. The potential for large-scale production and commercial application requires further investigation.
1：Experimental Design and Method Selection:
The phosphors were synthesized using the conventional solid-state reaction method.
2：Sample Selection and Data Sources:
High purity grade chemicals including strontium carbonate, aluminum oxide, and dysprosium oxide were used.
3：List of Experimental Equipment and Materials:
XRD (PANalytical), FESEM (Hitachi 6600), TEM (JEOL-JEM-2100 PLUS), Raman spectrometer (HORIBA), and spectrofluorometer (Horiba- Fluorolog BFL3-111).
4：1). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The mixed composition was sintered for 4 h at 1300°C under ambient condition.
5：Data Analysis Methods:
Structural analysis was performed using XRD, morphology and microstructure were analyzed using FESEM and TEM, and optical properties were analyzed using Raman and PL spectra.
