研究目的
To evaluate the effect of Nd3+ ion doping concentration on near-infrared laser emission in lead borate glassy materials.
研究成果
The 0.8 mol% Nd3+ doped LB glass shows the most intensive emission at 1.06 μm, making it suitable for NIR laser applications. The study demonstrates the importance of optimizing Nd3+ concentration to achieve maximum luminescence intensity without quenching.
研究不足
The study is limited to the concentration range of 0.2-1.0 mol% of Nd3+ in lead borate glasses. The luminescence intensity decreases beyond 0.8 mol% due to concentration quenching.
1：Experimental Design and Method Selection:
Nd3+ doped lead borate glasses were prepared by melt quenching technique. The optical properties were studied using XRD and optical absorption and emission spectroscopy.
2：Sample Selection and Data Sources:
Different concentrations (0.2-1.0 mol%) of Nd3+ doped LB glass systems were prepared.
3：2-0 mol%) of Nd3+ doped LB glass systems were prepared.
List of Experimental Equipment and Materials:
3. List of Experimental Equipment and Materials: Perkin-Elmer Lambda 950 spectrometer for absorption measurements, TRIX 550 monochromator for photoluminescence spectra and decay curves, SIEFERT diffractometer for XRD.
4：Experimental Procedures and Operational Workflow:
The raw materials were melted in an electronic furnace, quenched, and then polished for spectral measurements.
5：Data Analysis Methods:
Judd-Ofelt theory was applied to analyze the optical absorption spectra and predict radiative parameters.
