研究目的
To study synthesis methods and photoluminescence properties of ZrTiO4.
研究成果
The study concludes that the method of synthesis plays a vital role in determining the phase and morphology of ZrTiO4. Photoluminescence property depends on the phase of the material, with mixed phase ZrTiO4 showing both upconversion and down conversion luminescence. Solution combustion method and polymeric precursor method are effective for achieving ZrTiO4 nanoparticles at lower temperatures.
研究不足
The study focuses on the synthesis and photoluminescence properties of ZrTiO4, with limitations including the dependency of photoluminescent property on the phase of the material and the method of synthesis affecting morphology and phase.
1：Experimental Design and Method Selection:
The study employs solution combustion method and polymeric precursor method for the synthesis of ZrTiO4. Urea and glycine are used as fuels in the solution combustion synthesis.
2：Urea and glycine are used as fuels in the solution combustion synthesis. Sample Selection and Data Sources:
2. Sample Selection and Data Sources: Precursors include Titanium-tetra-butoxide, Zirconyl nitrate, Urea, and Glycine for solution combustion method; Titanium isopropoxide, Zirconium n-propoxide, citric acid, and glycerin for polymeric precursor method.
3：List of Experimental Equipment and Materials:
Equipment includes Rigaku DMax 2500 PC x-ray diffractometer, ULTRA 55 of GEMINI technology SEM, Perkin Elmer Spectrum version 10.4.3 instrument for FTIR, Shimadzu MPC3600 for UV-Vis-NIR spectroscopy, and Fluorimeter of pulsed xenon lamp for PL studies.
4：3 instrument for FTIR, Shimadzu MPC3600 for UV-Vis-NIR spectroscopy, and Fluorimeter of pulsed xenon lamp for PL studies. Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: For solution combustion synthesis, precursors are mixed and combusted in a preheated furnace at 500°C. For polymeric precursor method, metal-citrate chelate complex is formed and heated to initiate polyesterification, followed by calcination.
5：Data Analysis Methods:
XRD for crystallographic studies, SEM for morphology and elemental analysis, FTIR for transmission mode analysis, UV-Vis-NIR spectroscopy for reflectance, and PL studies for photoluminescence properties.
