| Research Abstract |
In blasting process light emission due to the collision between workpiece and blasting media can be observed. The intensity and the spectrum of luminescence depend on the blasting conditions. To monitor the light emission will be useful to decide blasting conditions and understand the blasting state. It is necessary to build a sensor system and glass will be suitable material for a sensor. The aim of this research is to realize the monitoring of light emission. In this study, substrate materials were irradiated by argon ion laser beam in sol-gel silica liquid. Stainless steel, silicon, indium were used as substrates. As a result, needle-shaped glass pillars with high aspect ratio were obtained and the growing rate depended on the solution temperature and substrate materials. Also poly-silazane is examined instead of sol-gel silica liquid, and transparent glass film was obtained.
