摘要: 利用溶胶-凝胶方法制备了1 wt% Bi2S3纳米晶掺杂钠硼硅玻璃. 利用X射线粉末衍射仪(XRD), X射线光电子能谱(XPS), 透射电子显微镜(TEM), X射线能量色散谱(EDX), 扫描模式透射电子显微镜(STEM)以及高分辨透射电子显微镜(HRTEM)对Bi2S3纳米晶在钠硼硅玻璃中的形貌和微结构进行了表征, 同时, 利用飞秒 Z 扫描技术在波长为770 nm对该玻璃的三阶非线性光学性能进行了分析测试. 结果表明, 尺寸为10~30 nm的Bi2S3正交晶系纳米晶在钠硼硅玻璃中形成, 该玻璃的三阶非线性光学折射率 γ 、三阶非线性吸收率 β 和三阶非线性极化率 χ (3) 分别为5.90×10 - 16 m2/W、7.35×10 - 9 m/W 和4.55×10 - 18 m2/V2.其中, 该玻璃的三阶非线性极化率值比未经掺杂的钠硼硅玻璃(χ(3)=1.09×10 - 22 m2/V2)高出4个数量级, 这表明, 随着Bi2S3纳米晶的引入, 该玻璃的三阶非线性光学性能将得到显著的提高.

Abstract: Bi2S3nanocrystals( 1wt%) embedded in sodium borosilicate glass were synthesized through Sol-Gel process. The morphology and microstructure of Bi2S3nanocrystals in sodium borosilicate glass were characterized by means of X-ray powder diffraction (XRD), X-rayphotoelectron spectroscope (XPS), transmission electron microscope (TEM),energy dispersion X-ray spectra (EDX), scanning transmission electronmicroscope (STEM) and high-resolutions TEM (HRTEM). Furthermore, the third-order nonlinear optical properties of the glass were measured by femtosecondZ -scan technique at a wavelength of 770 nm. The results show that the size of Bi2S3nanocrystals in sodium borosilicate glass usually ranges from 10 to 30 nm, and the Bi2S3 nanocrystals are determined to be of the orthorhombic phase. The third-order nonlinear optical refractive index γ, absorption coefficient β and susceptibility χ(3) of the glass are determined to be 5.90×10 - 16 m2/W, 7.35×10 - 9 m/W and 4.55×10 - 18 m2/V2, respectively. There into, the third-order optical nonlinear susceptibility χ(3) of the glass is four orders of magnitude greaterthan un-doped glass (χ(3)= 1.09×10 - 22 m2/V2). It is clear that the third-order nonlinearoptical properties of the glass will be improved greatly with an increase of the Bi2S3 content.
