研究目的
To study the effect of Sm3+ ions on the physical and spectroscopic properties of a ?uorophosphate glass host (40P2O5-30ZnO-20BaF2-3.8K2TeO3-1.2Al2O3-5Nb2O5) for display and laser material applications.
研究成果
The PZBKNA12 and PZBKNA13 glasses doped with Sm3+ ions exhibit unique luminescence parameters suitable for laser action, with high refractive index values and stimulated emission cross-sections, making them promising candidates for laser glass at 1.62 lm.
研究不足
The study focuses on the specific composition of phosphate glasses doped with Sm3+ ions, and the findings may not be directly applicable to other glass systems or dopants.
1：Experimental Design and Method Selection:
The glasses were prepared by a melt-quenching technique and characterized by x-ray diffraction, UV–visible–NIR, absorption, emission, and ?uorescence lifetime analysis.
2：Sample Selection and Data Sources:
The composition 40P2O5-30ZnO-20BaF2-
3：8K2TeO3-2Al2O3-5Nb2O5 in mol.% doped with Sm2O3 was used. List of Experimental Equipment and Materials:
A helium pycnometer (AccuPyc 1330, Micromeritics GmbH, Germany), x-ray diffraction (XRD; Siemens D 6000), UV VIS–NIR spectrophotometer (JASCO V-570), and a Thermo Scienti?c DXR Raman microscope with 532 nm excitation were used.
4：Experimental Procedures and Operational Workflow:
The glass samples were produced by melt-quenching, stirred inside the furnace with a platinum stirrer, annealed, and polished for optical measurements.
5：Data Analysis Methods:
The radiative properties were calculated using Judd–Ofelt (J–O) spectral intensity parameters.
