Upconversion Luminescence and Temperature Sensing Performance of TiO2-ZnO:Yb3+/Ho3+ Phosphors
In this study, TiO2-ZnO:Yb3+/Ho3+ upconversion phosphors are synthesized by a solid-phase reaction method and their Yb3+ concentration dependence is analyzed. The crystal structure of the phosphors is analyzed by X-ray diffractometry, where each sample is composed of Zn2TiO4 and Yb2Ti2O7. Photoluminescence characteristics are analyzed and peaks are observed at wavelengths of 539 nm (5F4, 5S2 → 5I8) and 669 nm (5F5 → 5I8). High intensity luminescence is obtained for samples with Yb = 7–8 mol%. Analysis of temperature characteristics shows absolute and relative sensitivities of 0.0052 K−1 and 0.40% K−1, respectively. The samples are found to be chemically stable, indicating that TiO2-ZnO:Yb3+/Ho3+ could be used as a temperature sensor.
期刊介绍：
The Brazilian Journal of Physics is a peer-reviewed international journal published by the Brazilian Physical Society (SBF). The journal publishes new and original research results from all areas of physics, obtained in Brazil and from anywhere else in the world. Contents include theoretical, practical and experimental papers as well as high-quality review papers. Submissions should follow the generally accepted structure for journal articles with basic elements: title, abstract, introduction, results, conclusions, and references.
