摘　　要：玻璃作为应用最广的光学材料,其性质不仅取决于其本身的化学组成,还可以通过向其中引入不同性质的纳米晶进行调控。当玻璃中引入贵金属等离激元纳米晶后,由于局域表面等离激元共振(LSPR)效应,会使得玻璃出现鲜艳的颜色。本文综述了各种含有贵金属、非贵金属等离激元纳米晶玻璃的光学性质及其制备方法,还讨论了近年来等离激元纳米晶玻璃在非线性光学以及超快光子学领域的应用。最后简要总结了等离激元纳米晶复合玻璃的研究现状以及潜在的发展方向。Because of properties such as wide band transparency,good chemical and thermal stability,low dispersion,high laser damage threshold and easy processing,glass is the most widely used optical material.Introducing nanocrystals into glass is commonly used to enhance the optical and electrical properties of glass.Metals,oxides,non-oxides,and semiconductors can be dispersed in glass-ceramics,and these nanocrystals precipitated in glasses can not only enhance the mechanical properties of the glass,but also provide properties that the glass substrate does not have.When these nanocrystals are introduced into glass,the bright color of the glass will appear due to the localized surface plasmon resonance(LSPR)effect.This optical effect based on the particle size can be interpreted as:the free electrons of metals limited to subwavelength nanoparticles will have LSPR under certain frequency excitation.This effect will cause the electric field near the surface of the nanoparticles to increase by 3 to 6 orders of magnitude,thus greatly promoting the interaction between light and matter,and it shows the strong linear absorption in the resonance band.Its absorption cross-section is at least 2 orders of magnitude larger than that of quantum dots,organic dyes and various optically active ions.Among the different compositions of nanocrystals,precious metal nanocrystals may be one of the earliest used by human society.In most oxide glass systems(such as silicate glass systems),noble metals such as Au,Ag,and Pt are difficult to form stable chemical bonds with the glass network.After heat treatment,these metal elements are easy to precipitate in clusters or nanocrystals.At present,a variety of noble metal nanocrystalline doped glass systems have been widely studied.In addition,some other plasmon materials such as non-precious metals can also be precipitated from some specific compositions of glass.Except noble metal,nanocrystals that now can be precipitated from glass include oxide and non-oxide systems such as ZnO:Sb,Cu_(2–x)Se,RuO_(
