Ultra-high Quality factor (Q value) can be accomplished in a microsphere as optical cavity structure, thus in the cavity ultimate interaction between light and materials is achieved. The following results were obtained by this research.(1) Excitation of microsphere(a) Optical fiber coupler to a sphere was fabricated by abbreviation of bending single-mode optical fiber that was buried in a resin. High refractive index glass spheres (n_D=1.93) were set up on the coupler, and Resonant Raman scattering originated from optical fiber and glass sphere were observed.(b) Coating was carried out on the high-index glass sphere (n_D=1.93, diameter 30μm), and the terrace portion formed on the coating layer was dramatically increased the Raman scattering intensity. By this sphere, Stimulated Raman emission achieved.(2) Fabrication of nanoparticle-doped maicrospheres.Gold and ZnO nanoparticles was prepared by the sol-gel technique. They can be incorporated stably into the hybrid microspheres.

微球作为光腔结构可以实现超高的品质因数（Q值），从而在腔内实现光与材料的最终相互作用。（1）微球的激发（a）。 ) 球体光纤耦合器是通过将埋在树脂中的高折射率玻璃球体（n_D=1.93）弯曲的简称制成的，并在耦合器上进行谐振。观察到源自光纤和玻璃球的拉曼散射。(b)对高折射率玻璃球(n_D=1.93，直径30μm)进行涂层，涂层上形成的平台部分显着增加了拉曼散射通过该球体，实现了受激拉曼发射。(2)纳米颗粒掺杂微球的制备。采用溶胶-凝胶技术制备了金和ZnO纳米颗粒。可以稳定地掺入杂化微球中。
