| Summary: | By using a solar furnace, yttrium oxide crystals were grown by the fusion process. The crystals obtained were highly transparent in the spectral region from 0.25 to 9.6 µ. The refractive index in this region was measured by three different methods. The observed index values were well expressed by the dispersion formula. From the values of parameters in the formula, it was found that the center of the fundamental absorption and the lattice absorption were at about 0.139 and 22.9 µ, respectively. A brief discussion on the infrared and ultraviolet absorption edges is added. |
