摘要
Microspheres of refractive index of n(D) >2 have been investigated. The organic-inorganic hybrid microspheres of refractive index n(D)=1.70 - 1.72 were prepared at room temperature by the vibrating orifice technique using titanium alkoxide and silane coupling reagents as starting materials. Subsequently heating the microspheres at 400 - 450 degreesC resulted in increasing their refractive indices to n(D)=2.10 - 2.25 with keeping good spherical shape. Rhodamine 6G-doped microspheres of n(D)=1.72 were also prepared at room temperature and the lasing from them was performed by pumping by second-harmonic pulses of Q-switched Nd-yttritium-aluminum-garnet laser.
