Paper Abstract

The effects of heat treatment on the optical quality of organic-norganic hybrid spherical particles were investigated. The spherical particles with a diameter of 6μm were prepared via sol-gel process from phenyl-tetraethyl-silane(PTES) using the vibrating orifice technique, and they showed strong oscillation signals based on the spherical resonance mode with low power threshold of the incident CW-Ar+ laser. Against the heat treatment on the slide glass plate, there were some particles which remained their spherical shape after 400°C heating depending on the condition of sol preparation. The survived particles were also found to have high photo-stability that they were not damaged from the laser irradiation of 514.5nm Ar+ light with a power >120mW/particle, while as-prepared particles were bursted by the irradiation <20mW/particles. From the measurements of micro Raman scattering spectroscopy, optical and secondary electron microscope and thermal analysis, the thermal stability of hybrid materials was considered.
