这项研究的目的是研究在可见光谱中掺杂钕(Nd3)稀土离子的氟氧化物玻璃的新型组成。这一领域在现有文献中没有得到广泛的研究,因此,了解电磁频谱的这一部分中有利的光致发光特性至关重要。因此,我们合成并表征了掺杂1%钕(Nd3)离子的SiO2-PbO-PbF2(SPF)玻璃。光谱分析,基于Judd-Ofelt理论,进行了吸收光谱。这些分析能够确定吸收截面,转移概率,以及不同跃迁的Judd-Ofelt强度参数Ω2,Ω4和Ω6。此外,我们计算了各种辐射特性,如支化比,集成横截面,辐射寿命,发射横截面,光学增益,和多色行为(色度坐标,CIE图)在不同激发波长下。结果表明,使用这些掺杂有Nd3作为荧光团的氟氧化物硅酸盐玻璃具有广阔的前景。潜在的激光材料约630纳米发射和其他光子应用。
The aim of this research is to investigate novel compositions of oxyfluoride glasses doped with
Neodymium (Nd3+) rare earth ions in the visible spectrum. This area has not been extensively studied in the existing literature, so it is vital to understand the favorable photoluminescence characteristics within this part of the electromagnetic spectrum. Therefore, we synthesized and characterized SiO2-PbO-PbF2 (SPF) doped with 1%
neodymium (Nd3+) ions glasses. Spectroscopic analyses, based on Judd-Ofelt theory, were conducted on absorption spectra. These analyses enabled to determine absorption cross-sections, transition probabilities, and Judd-Ofelt intensity parameters Ω2, Ω4, and Ω6 for the different transition. Additionally, we calculated various radiative properties, such as branching ratios, integrated cross-sections, radiative lifetimes, emission cross-section, optical gain, and the multicolor behavior (chromaticity coordinates, CIE diagram) under different excitation wavelengths. The results suggest promising prospects for using these oxyfluoride silicate glasses doped with Nd3+ as a fluorophore, potentially for lasing materials around 630-nm emission and in other photonic applications.
