FLUORIDE GLASSES CONTAINING RARE EARTH

【摘要】 <正> Fluoride glasses containing rare earths exhibit interesting spectroscopic properties.They have widetransmission range from 0.25μm in the UV to 7μm in the IR,allowing observation,in a vitreous material,ofabsorption and emission bands in a large optical range.The absorption spectra of fluoride glasses with rareearth substitutions are found to vary with the rare earth ions used.The T_g~’s for these glasses average out at311℃.Optical properties,such as refractive indices are not obviously influenced by rare earth substitutions.更多还原
