In recent years,rare-earth materials have garnered significant attention due to their unique upconversion luminescent properties.Co-precipitation method was used to successfully prepare YF3 upconversion luminescent materials doped with Yb3+ and Er3+.In order to enhance crystal crystallinity and eliminate the impact of oxygen impurities,researchers innovatively employed a dehydration and deoxygenation treatment at 500℃ in an HF/H2 atmosphere.Comprehensive characterization was conducted through various techniques,including XRD,oxygen analyzer,infrared absorption spectroscopy,and fluorescence spectroscopy.The results demonstrated that the samples treated with high-temperature deoxygenation in an HF/H2 atmosphere exhibited higher crystallinity and superior luminescent performance,displaying elevated quantum yields.The study unveiled the adverse effects of oxygen impurities on the performance of YF3∶Yb3+,Er3+ upconversion luminescent materials,while application of high-temperature HF/H2 atmosphere treatment was an effective approach for improving luminescent performance,providing new insights for similar luminescent material researches.
