| Research Abstract |
Physical properties, e.g., refractive index and thermal expansion, of glass materials can be controlled with addition of dopants. Evaluation techniques for fabricated glasses are important to obtain glasses having the desired properties. In this study, acoustic properties (leaky surface acoustic wave velocity, longitudinal velocity, and density) were measured by the ultrasonic microspectroscopy technology. Relationships among acoustic properties, fictive temperature, OH concentration, and Cl concentration were obtained. We also obtained relationships among acoustic properties, F concentration, and fictive temperature for F-doped synthetic silica glasses.
