High-Temperature Spectral Emittance of Oxides of Erbium, Samarium, Neodymium and Ytterbium

Normal spectral emittance data are reported for solid specimens of the oxides of erbium, samarium, neodymium, and ytterbium. The spectral emittance has been characterized over the spectral range of 0.5–5.0 µ and at sample temperatures from 1540 up to 1870 K.
