研究目的
Investigating the synthesis, characterization, and up-conversion luminescence properties of hollow GdF3 ellipsoids for potential applications in laser, bioanalysis, optoelectronic, and nanoscale devices.
研究成果
Uniform and well-dispersed hollow GdF3 ellipsoids were successfully synthesized via a hydrothermal method. The UC luminescence properties were systematically investigated, showing multicolor emissions under 980 nm excitation. The ability to produce white light by adjusting doping concentrations suggests potential applications in color displays, back light, UC lasers, and photonics.
研究不足
The study focuses on the synthesis and luminescence properties of hollow GdF3 ellipsoids but does not explore their application in specific devices or systems in depth.
1：Experimental Design and Method Selection:
A hydrothermal method was used for the synthesis of hollow GdF3 ellipsoids.
2：Sample Selection and Data Sources:
GdCl3 and NaBF4 were used as precursors.
3：List of Experimental Equipment and Materials:
D8 Focus diffractometer (Bruker), field-emission scanning electron microscopy (Hitachi S4800), FEI Tecnai G2 S-Twin transmission electron microscope, 980 nm continuous wave laser (K98D08M-30W, China), spectrophotometer (Avaspec-2048L-USB2).
4：2). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: GdCl3 and NaBF4 were mixed, stirred, and then subjected to hydrothermal treatment at 180°C for 24 h. The products were characterized by XRD, SEM, TEM, and UC luminescence spectroscopy.
5：Data Analysis Methods:
XRD patterns were analyzed for crystallinity and phase purity. SEM and TEM images were used for morphology and size analysis. UC emission spectra were recorded under 980 nm excitation.
