基于用各种金属和纳米颗粒掺杂玻璃来控制玻璃的颜色和性质的技术被广泛使用。在本文中，我们证明了在石英玻璃中的镍球的迁移所造成的激光照射伴随着镍纳米粒子沉淀的球迁移轨迹。在迁移过程中，镍球的直径减小。在半径达50 μ m的区域中观察到直径为数百纳米的结晶纳米颗粒，这些纳米颗粒形成四个圆柱形同轴层，在迁移方向上以10-20 μ m的间隔具有条纹。2015美国光学学会Optical Society of America
Techniques to control the colors and properties of glasses based on doping of the glasses with various metals and nanoparticles are widely used. In this paper, we demonstrate the migration of a nickel sphere in silica glass caused by laser illumination accompanied by nickel nanoparticle precipitation in the sphere migration trajectory. During migration, the diameter of the nickel sphere decreased. Precipitated nanoparticles with diameters of several hundred nanometers were observed in areas of up to 50 mu m in radius and these nanoparticles formed four cylindrical coaxial layers with stripes at 10-20 mu m intervals in the migration direction.
