研究目的
To investigate the mid-infrared emission performance of different doping concentrations of Dy3+/Tm3+ in ZBYA glasses for efficient 2.9 μm mid-infrared laser applications.
研究成果
The Dy3+/Tm3+ co-doped ZBYA glass exhibits strong λ~2.9 μm mid-infrared emission due to efficient energy transfer from Tm3+ to Dy3+ ions. This makes it a promising candidate material for 2.9 μm mid-infrared laser applications. Future work could focus on the preparation of ZBYA glass fiber for mid-infrared laser applications.
研究不足
The study is limited to the analysis of Dy3+/Tm3+ co-doped ZBYA glasses and does not explore other doping combinations or glass matrices. The practical application in high-power fiber lasers may be constrained by the glass's thermal and chemical properties.
1：Experimental Design and Method Selection:
The study involved preparing Dy3+/Tm3+ co-doped ZBYA glass samples by the melt-quenching method and analyzing their spectroscopic properties through absorption and emission spectra. The Judd-Ofelt theory was used to calculate spontaneous radiative transition probabilities, branching ratios, and radiative lifetimes.
2：Sample Selection and Data Sources:
High-purity ZrF4, BaF2, YF3, AlF3, DyF3, and TmF3 powder precursors were used to prepare the glass samples.
3：List of Experimental Equipment and Materials:
A Perkin-Elemer Lambda 900 UV spectrophotometer, a Perkin Elmer FT-IR spectrometer, a Horiba LabRAM HR Evolution spectrometer, and a Zolix Omni-λ3015 infrared monochromator were used for measurements.
4：Experimental Procedures and Operational Workflow:
The raw materials were mixed, melted, poured onto a preheated copper plate, annealed, and then cut and polished for measurements.
5：Data Analysis Methods:
The emission cross-section and gain cross-section were calculated using the McCumber theory and Judd-Ofelt theory, respectively.
