    摘要： A fluorophor which comprises as a main component, an α type sialon crystal containing at least Li, A element (wherein A represents one or more elements selected from among Mn, Ce, Pr, Nd, Sm, Eu, Tb, Dy, Er, Tm and Yb), M element (wherein M represents one or more metal elements except Li and the A element), Si, Al, oxygen and nitrogen. The fluorophor has an a type sialon crystal structure which is represented by the general formulae: (Lix1, Ax2, Mx3)(Si12−(m+n)Alm+n)(OnN16−n) 1.2≦x1≦2.4 (1) 0.001≦x2≦0.4 (2) and 0≦x3≦1.0 (3), and has a luminescence peak at a wavelength in the range of 400 to 700 nm. The above phosphor is reduced in the lowering of brightness, and can be suitably used for a white LED and the like.

    摘要： The present invention provides a lanthanum sulfide or cerium sulfide sintered compact usable as a thermoelectric conversion material having a high Seebeck coefficient. The sintered compact has a chemical composition of La2S3 or Ce2S3, and a crystal structure consisting of a mixture of beta and gamma phases having a Seebeck coefficient higher than that of the crystal structure otherwise being in gamma single-phase. The sintered compact is produced by preparing a beta-phase La2S3 or alpha-phase Ce2S3 powder of raw material having a high purity with a suppressed carbon impurity concentration and a given range of oxygen concentration, charging the raw material into a carbon die having an inner surface covered with an h-BN applied thereon, and hot-pressing the charged material under vacuum to form a mixture of beta and gamma phases having a high Seebeck coefficient.
