Optical and optoelectronic glasses by sol-gel

Application of the sol-gel method to the fabrication of opticallyhigh-performance bulk glasses has been tried by many researchers in the world. Although to date ithas not been as successful as was expected at the beginning, there exist various high-performanceglasses which will be prepared more advantageously by the sol-gel method than with conventionalglass fabrication process. These are all promising materials and will appear in optical andoptoelectronic devices in the near future.
