Lasing from a dye-doped microsphere was performed from the coupling between fluorescent dye molecules and morphology-dependent-resonances. Using phenyl triethoxy silane (PTES) as a starting material, I made Rhodamine 6G-doped spherical particles of organic-inorganic hybrid material by sol-gel technique. From the particles of 4-6 mm in diameter, a strong laser emission at 598 nm wavelength was confirmed by pumping a pulse laser light of 532 nm wavelength.Since particle size control, good circularity, smooth surface are required for the spherical cavity structure, in this study, the formation techniques for preparing spherical particles have been investigated. Processing steps for preparing dye-doped particles are consisted of two major processes ; (1) Hydrolysis and polymerization of PTES, and (2) Solidification of liquid droplets. For the second process two elaborate techniques to make dye-doped microspheres were developed : (a) Emulsion technique in liquid phase, (b) Vibrating orifice technique in gas phase. Especially the vibrating orifice technique enables us to obtain monodispersed microspheres of optical cavity structure.

利用荧光染料分子与微球形貌相关共振的耦合，实现了染料掺杂微球的激光发射。以苯基三乙氧基硅烷（PTES）为原料，采用溶胶-凝胶法制备了罗丹明6 G掺杂的有机-无机杂化材料球形粒子。用波长为532 nm的脉冲激光泵浦直径为4-6 mm的颗粒，证实了其在598 nm波长处有较强的激光发射。由于球形腔结构要求颗粒尺寸可控、圆度好、表面光滑，因此本研究对球形颗粒的制备技术进行了研究。用于制备染料掺杂颗粒的加工步骤由两个主要过程组成：（1）PTES的水解和聚合，以及（2）液滴的固化。对于第二种方法，开发了两种制备染料掺杂微球的精细技术：（a）液相乳液技术，（B）气相振动孔技术。特别是振动孔技术，使我们能够获得单分散的光学腔结构的微球。
