| Research Abstract |
Ceramic glaze contained erbium was coated on polycrystalline alumina to enhance emittance of the alumina in the wavelength around 1.5. m by means of submerged-substrate method proposed in this study. Spectral distribution of normal emittance of the coated alumina was measured under the condition of the temperature 1273 K. It was revealed that the emittance in the emissive band around 1.5. m increases with the film thickness and content of Er, and then, approaching to the almost maximum value. Furthermore, we succeeded in coating Er-doped ceramic glaze with thickness of 0.05 mm by means of blade coating method.
