摘要

本文报道了掺杂Ag2O和Gd2O3-Ag2O的LiKB4O7硼酸盐玻璃的非线性光学研究结果。结果表明，经过退火处理后，在玻璃基体的亚表面层内形成了直径为3.8 ~ 7.6 nm的银纳米颗粒。由于纳米粒子激发了局部表面等离子体共振，极大地增强了硼酸盐玻璃固有的非线性光学响应。非线性折射系数n2和非线性吸收系数β采用单束z扫描技术测定。研究结果可能在光子和光电子器件中得到应用。

Enhanced Nonlinear-Optical Response of LiKB4O7 Glass Containing Ag Nanoparticles

We present the results on nonlinear-optical studies of LiKB4O7 borate glass doped with Ag2O and Gd2O3-Ag2O. It was found that annealing of the glasses results in the formation of 3.8-7.6 nm in diameter Ag nanoparticles within thin sub-surface layer of glass matrix. The nanoparticles greatly enhance inherent nonlinear-optical response of borate glass due to the excitation of localized surface plasmon resonance in the nanoparticles. Nonlinear refraction n2 and nonlinear absorption β coefficients were determined using single-beam Z-scan technique. The results may find applications in photonic and optoelectronic devices.
