近年来,由金属微粒弥散相与氧化物电介质(玻璃或陶瓷)基体所构成的复合材料体系引起了人们的关注。由于这类材料在光学(光吸收、散射、非线性)、电学(隧穿效应,电致发光)、磁学及催化等方面均有一些特殊性质,使这类材料体系在理论研究和实际应用方面都具有很高的价值。目前,这类材料的制备主要是采用溅射法和溶胶-凝胶(Sol-gel)法。限于技术上的原因,上述材料的基体主要局限于一些简单的氧化物体系,包括SiO_2,Al_2O_3和ZrO_2。
In recent years, a composite material system composed of a metal microparticle dispersion phase and an oxide dielectric (glass or ceramic) matrix has aroused people's attention. Due to the special properties of such materials in the fields of optics (light absorption, scattering, nonlinearity), electrical (tunneling, electroluminescence), magnetism and catalysis, such material systems have made theoretical and practical applications All have high value. Currently, the preparation of such materials is mainly the use of sputtering and sol-gel (Sol-gel) method. For technical reasons, the matrix of the above materials is mainly confined to simple oxide systems including SiO 2, Al 2 O 3, and ZrO 2.
