The thermometric performance of TCL of Er3+ ions in different host lattices is closely linked with the microscopic properties of crystals. The quantitative relationships established allow for the prediction of thermal coupled thermometric performance, facilitating the design of nanothermometers.
研究不足
The study focuses on a specific set of host lattices and may not cover all possible materials. The influence of doping concentrations on the host structure is considered minor but could introduce errors.
1：Experimental Design and Method Selection:
The study involves the synthesis and characterization of Er3+/Yb3+ co-doped host lattices, including Y3Al5O12 (YAG), YbPO4, YPO4, LaAlO3, Lu2O3, Y2O3, Gd2O3, La2O3, YVO4, and GdVO
2：The luminescence properties under 980 nm excitation are analyzed. Sample Selection and Data Sources:
Samples are selected based on their potential as host lattices for Er3+/Yb3+ co-doping. Data is acquired through emission spectra analysis under varying temperatures.
3：List of Experimental Equipment and Materials:
The materials include various host lattices doped with Er3+/Yb3+. Equipment details are not specified in the abstract.
4：3+. Equipment details are not specified in the abstract. Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The procedure involves synthesizing the doped materials, measuring their emission spectra under 980 nm excitation, and analyzing the temperature-dependent luminescence intensity ratio (LIR).
5：Data Analysis Methods:
The LIR values are fitted using Boltzmann's law to estimate B and ΔE values. The correlation between these values and the microscopic properties of crystals is explored using the chemical bond theory of complex crystals.
