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。本研究取得了以下成果。(1)微球的激发（a）通过弯曲埋在树脂中的单模光纤的缩写来制作光纤耦合器到球体。在耦合器上放置高折射率玻璃球（n_D=1.93），观察到光纤和玻璃球的共振拉曼散射。(b)在高折射率玻璃球（n_D=1.93，直径30μm）上进行镀膜，镀膜层上形成的台阶部分显著提高了拉曼散射强度。通过这种球，实现了受激拉曼发射。(2)纳米粒子掺杂微球的制备采用溶胶-凝胶法制备了金和氧化锌纳米粒子。它们可以稳定地掺入到杂化微球中。
