Abstract
Luminescence of Incandescent Oxides.—Some oxides, when heated to a temperature lying within a definite and sometimes narrow range, emit radiation in a limited region of the spectrum far in excess of the radiation emitted in that region by a black body at the same temperature. The excess is ascribed to luminescence. As a striking example, the blue radiation from niobium oxide at 560° C. is about 85,000 times the corresponding radiation from a black body, the ratio decreasing with increasing temperature until it is 1.35 at 1037° C. just before the oxide melts.
