本文综述了准分子激光脉冲激光修饰非晶态介质（如硅酸盐玻璃）中离子注入合成的金属纳米粒子。低离子注入制备的复合材料样品的主要特征之一是在辐照基底表面的深度能量中生长出尺寸分布非常宽的金属颗粒。脉冲激光照射可以修饰该复合层，提高纳米颗粒尺寸分布的均匀性。脉冲激光照射引起的变化表明，银纳米颗粒的平均尺寸减小，银在玻璃中的长期溶解。这对于获得非线性光学材料的技术的发展尤其有希望。为了控制得到的层的参数，采用了一种基于对玻璃植入面和后表面测量的光学反射光谱分析的方法。讨论了影响实验的因素，并利用Mie理论建立了纳米粒子在玻璃中的消光光谱模型。
The present review concentrates on the excimer laser pulse laser modification of metal nanoparticles synthesized by ion implantation in amorphous dielectrics such as silicate glasses. One of the main features of composite samples prepared by the low ion implantation is the growth of metal particles with a very wide size distribution in the depth energy from the irradiated substrate surface. Pulsed laser irradiation makes it possible to modify this composite layer, improving the uniformity in the size distribution of the nanoparticles. Changes induced by pulsed laser exposure suggest there are both reductions in average size of the silver nanoparticles, and some long range dissolution of silver in the glass. This is particularly promising for the development of the technology of obtaining nonlinear optical materials. To control the parameters of the obtained layers a method based on an analysis of the optical reflection spectra measured on the side of the implanted and rear surfaces of glass is applied. Also, the factors influencing the experiment are discussed and the optical extinction spectra of the nanoparticles in the glass are modeled using the Mie theory.
