Abstract

The invention discloses an ITO nanoparticle-doped glass and a preparation method thereof. Porous glass with uniformly distributed nano-sized micropores is used, and ITO nanoparticles are prepared in the micropores in situ, so that the sizes of the particles can be effectively limited and the ITO nanoparticles have good dispersion in the glass; the ITO nanoparticle-doped glass is simple in process and convenient to prepare; after high-temperature sintering, the pores of the porous glass are closed, so that the strength of the glass is greatly improved; the ITO nanoparticles are uniformly dispersed in the glass, so that the short-wave luminous performance of the glass is significantly improved. The ITO nanoparticles are uniformly dispersed in a glass matrix, and in combination with high chemical stability of silicon dioxide glass, the ITO nanoparticle-doped glass can better play unique non-linear characteristic, plasma characteristic and defect luminescence characteristic and other characteristics of ITO itself, and is applied to the fields of nonlinear optics, fluorescence enhancement, surface plasma sensing, photocatalysis, optical fiber communication and the like.
