研究目的
Examining the relationship between the luminescence properties of Pr3+ and the chemical composition of the glass, and demonstrating the luminescence properties of Pr3+-doped aluminosilicate glasses.
研究成果
The study demonstrated the luminescence properties of Pr3+-doped aluminosilicate glasses, showing a faster decay on the order of nanoseconds. Although P doping improved the optical absorption and QE, its effects were not observed in X-ray-induced scintillation or neutron-induced pulse height spectra due to different energy conversion mechanisms.
研究不足
The internal quantum efficiency of Pr3+-doped glasses is not as high as that of conventional Ce3+-doped glasses. The effect of P doping was not observed during X-ray induced scintillation or in the pulse height spectra under 252Cf irradiation.
1：Experimental Design and Method Selection:
The study focused on the luminescence properties of Pr3+-doped aluminosilicate glasses prepared in air, measuring PL and X-ray-induced scintillation properties of glasses with different Pr3+ concentrations.
2：Sample Selection and Data Sources:
The glasses were prepared with different amounts of Pr3+ and some were codoped with phosphorus.
3：List of Experimental Equipment and Materials:
A TG8120 differential thermal analysis system, U4150 UV–vis–NIR spectrophotometer, F7000 fluorescence spectrophotometer, Fluorolog instrument, Quantaurus-QY instrument, and an X-ray-induced scintillation system were used.
4：Experimental Procedures and Operational Workflow:
The glasses were melted, annealed, and polished before measurements. PL, PLE, emission decay, QE, X-ray-induced scintillation, and pulse height spectra were measured.
5：Data Analysis Methods:
The data were analyzed to understand the luminescence properties and the effects of Pr3+ concentration and P codoping.
