This paper reports the influence of antimony ions and Sb2O3 reduced Ag0 on the magnetic and Faraday rotation of diamagnetic glasses for the first time. High Verdet constant diamagnetic glasses with compositions of xSb2O3–(15–x)B2O3–35PbO–45Bi2O3–2Ag2O–3ZnO were fabricated and characterized. Ag nanoparticles were realized in glass using Sb2O3 as reducing agent through single-step melting quenching technique. The structure, spectral along with optical, magnetic and Faraday rotation properties were investigated through XRD, FT-IR, Raman, XPS, UV-VIS, luminescence and VSM measurements. Due to the big optical basicity of glass matrix and the reducing property of Sb2O3, Ag+ ions were reduced to Ag0 accompanied with the conversion from Sb3+ to Sb5+. Raman spectra revealed the presence of SbO3, BiO3, PbO4, and BO3, BO4 units in glasses, with the increase of Sb2O3, Ag-O and B-O vibration decreased and 10-15% Sb2O3 doped samples crystallized into ceramics. XPS analysis displays the co-existence and evolutions of antimony and silver species as a function of Sb2O3 content. SPR absorption peaks of Ag nanoparticles in glasses red-shifted from 525nm to 600nm, indicating the aggregation of Ag nanoparticles into bigger sized Ag3 clusters which present emission peaks around 560nm. The electron transitions between Sb3+ and Sb5+ show emission around 560nm while Sb5+ ions show emission at 800nm. All glasses exhibited diamagnetic properties due to the diamagnetic character of glass matrix and doping ions. Both the high polarizability of diamagnetic Sb3+&Sb5+ and Ag0 SPR effects contributed to an enhancement of Faraday rotation of glasses, the 3%Sb2O3 doped glass showed the highest Verdet constant of 0.2047min/G.cm at 594nm which therefore might be an attractive candidate for magneto optical device applications.

玻璃中Sb 2 O 3的等离激元,光致发光和法拉第旋转

本文首次报道了锑离子和Sb 2 O 3还原的Ag 0对反磁性玻璃的磁性和法拉第旋转的影响。高维尔德常数的反磁性眼镜XSB的组合物2 ö 3 - (15-x)B 2 ö 3 -35PbO-45Bi 2 ö 3 -2Ag 2 O形3ZnO被制造和表征。使用Sb 2 O 3在玻璃中实现了银纳米颗粒通过一步熔融淬火技术还原为还原剂。通过XRD,FT-IR,拉曼,XPS,UV-VIS,发光和VSM测量研究了结构,光谱以及光学,磁性和法拉第旋转特性。由于玻璃基体的强光学碱性和Sb 2 O 3的还原性能,伴随着Sb 3+向Sb 5+的转化,Ag +离子被还原为Ag 0。拉曼光谱表明,随着Sb 2 O的增加,玻璃中存在SbO 3,BiO 3,PbO 4和BO 3,BO 4单元。如图3所示,Ag-O和BO的振动降低,并且10-15%的Sb 2 O 3掺杂的样品结晶成陶瓷。XPS分析显示锑和银物种共存和演变与Sb 2 O 3含量的关系。玻璃中的银纳米颗粒的SPR吸收峰从525nm红移到600nm,表明银纳米颗粒聚集到更大尺寸的Ag 3簇中,在560nm附近出现了发射峰。Sb 3+和Sb 5+之间的电子跃迁在560nm处发射,而Sb 5+离子在800nm处显示发射。由于玻璃基质和掺杂离子的抗磁特性,所有玻璃均表现出抗磁特性。抗磁性Sb 3+和Sb 5+的高极化率以及Ag 0 SPR效应都有助于增强玻璃的法拉第旋转,掺杂3%Sb 2 O 3的玻璃在594nm处显示出最高的Verdet常数,为0.2047min / G.cm。因此对于磁光器件的应用可能是一个有吸引力的候选者。
