研究目的
To study the effect of chloride ions on the properties of Er3+-doped fluorozirconate glass, focusing on glass-forming abilities and fluorescence properties.
研究成果
The introduction of chloride ions into Er3+-doped fluorozirconate glass causes nonlinear changes in glass-forming abilities and fluorescence properties. These changes are attributed to structural modifications and variations in phonon density. The research provides new insights into the anion modification of fluoride glasses.
研究不足
The study focuses on the effects of chloride ions on Er3+-doped fluorozirconate glass, and the findings may not be directly applicable to other types of glass or dopants. The nonlinear changes observed require further investigation to fully understand the underlying mechanisms.
1：Experimental Design and Method Selection:
The study involved the systematic replacement of fluoride ions with chloride ions in Er3+-doped fluorozirconate glass to observe changes in glass-forming abilities and fluorescence properties.
2：Sample Selection and Data Sources:
Samples were prepared with varying concentrations of chloride ions, labeled as Zx (x = 0; 1; 2; 5; 8; 10; 15; 20).
3：0). List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: Philips PANalytical X'Pert X-ray diffraction (XRD) system, EXSTAR SII:TG/DTA7300, Raman spectrometer (Jobin Yvon), Lambda750 UV/VIS/NIR spectrophotometer (Perkin Elmer), FLSP 920 (Edinburgh Instruments Ltd.).
4：Experimental Procedures and Operational Workflow:
Glass samples were prepared using conventional melt-quenching techniques, melted at 850°C for 30 min, poured on a preheated brass mold, annealed, and polished for testing.
5：Data Analysis Methods:
The experimental oscillator strength and Judd-Ofelt intensity parameters were calculated and discussed to analyze the fluorescence properties.
