Lead-nanoparticles-doped Na2O-B2O3-SiO2 (NBS) glass was prepared by sol-gel and atmosphere control methods.The formation mechanism and the microstructure of the specimens were investigated by differential thermal analysis and thermal gravimeter, X-ray diffraction, transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray spectroscopy, and nitrogen adsorption measurements, respectively.The linear and nonlinear optical properties of the glass were analyzed by UV/VIS/NIR spectrophotometry and Z-scan technology.The results showed that the Pb nanoparticles in spherical shape with the average particle size about 18.9 nm belong to cubic crystal system and have good crystallinity and dispersibility in the glass matrix as well as exhibit excellent nonlinear optical properties.The specimen has a high linear optical transmittance, and little absorption peaks appear in the examined wavelength range.The third-order optical nonlinear parameters calculated are γ of 1.67 × 10-16 m2/W, β of 7.02 × 10-11 m/W, and x(3) of 2.61 × 10-17 m2/W2.

硫系玻璃具有优异的红外传输性能、高的三阶非线性折射率、较好的玻璃态稳定性和化学稳定性,被认为是较理想的红外光学非线性材料.然而,硫系玻璃普遍存在光致折射率变化现象,严重影响非线性光学器件的工作稳定性.研究表明,平均配位数(MCN)为2.45-2.50的Ge-As-Se硫系玻璃具有极小的光致变化效应.据此我们尝试了以Ge 10.5As25 Se64.5 (MCN=2.46)作为芯玻璃制备具有芯包结构
