Optical fibers containing gold metal nanoparticles were developed by modified chemical vapor deposition, in which Au(OH)3 and tetraethyl-orthosilicate (TEOS) was used via sol-gel process to incorporate gold metals by providing the reduction atmosphere. The absorption peak appeared near 490 nm was found to be due to the surface plasmon resonance of the gold nanoparticles incorporated in the fiber core.
通过改进的化学气相沉积法制备了含有金金属纳米颗粒的光纤，其中通过溶胶 - 凝胶法使用Au(OH)3和正硅酸四乙酯（TEOS），通过提供还原气氛来掺入金金属。发现出现在490nm附近的吸收峰是由于掺入光纤芯中的金纳米颗粒的表面等离子体共振所致。
