研究目的
Investigating the synthesis and photoluminescence properties of Ca4La6(PO4)2(SiO4)4O2:Dy3+ phosphor for application in white light-emitting diodes.
研究成果
The Dy3+-activated CLPSO phosphors exhibit high thermal stability and suitable photoluminescence properties, making them promising candidates for near-UV white light-emitting diodes.
研究不足
The study focuses on the synthesis and properties of a specific phosphor, and its application is limited to white light-emitting diodes. Further optimization may be required for other applications.
1：Experimental Design and Method Selection:
High-temperature solid-state reaction method was used for synthesis. The crystal structure, diffuse reflection, photoluminescence, and photoluminescence excitation spectra, decay curves, as well as thermal stability were investigated.
2：Sample Selection and Data Sources:
Starting materials were CaCO3, La2O3, (NH4)H2PO4, SiO2, and Dy2O
3：List of Experimental Equipment and Materials:
X-ray diffractometer (Bruker D8 Advance), fluorescence spectrophotometer (Edinburgh FS5), UV/visible spectrophotometer (UV-3600, SHIMADZU), and spectrophotometer (Edinburgh Instruments, FLS980).
4：0). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Materials were mixed, ground, preheated at 600 ℃ for 3 h, sintered at 1400 ℃ for 4 h, and then furnace-cooled.
5：Data Analysis Methods:
XRD patterns, PL, PLE, temperature-dependent luminescence spectra, and decay curves were analyzed.
