て有用な新規化合物を提供する。[Table] This compound can be produced by the following method. Metallic lutetium or lutetium oxide or a compound that is decomposed into lutetium oxide by heating; Metallic gallium or gallium oxide or a compound that is decomposed into gallium oxide by heating;
Metallic zinc or zinc oxide or a compound that is decomposed into zinc oxide by heating is
Mixing Zn at an atomic ratio of 1:1:2,
It can be produced by heating the mixture at a temperature of 600° C. or higher in the air, in an oxidizing atmosphere, or in a reducing atmosphere in which Lu and Ga are not reduced to a trivalent ion state and Zn is not reduced to a divalent ion state. It will be done. Commercially available starting materials used in the present invention may be used as they are, but in order for the chemical reaction to proceed quickly, it is better to have a small particle size, especially 10 μm.
It is preferable that it is below. Further, when used as an optical functional material or a semiconductor material, it is preferable to have high purity since contamination with impurities is avoided. Examples of compounds whose starting materials yield metal oxides by heating include hydroxides, carbonates, and nitrates of the respective metals. The raw materials are thoroughly mixed as they are or together with alcohols, acetone, etc. The mixing ratio of the raw materials needs to be such that the ratio of Lu, Ga, and Zn is 1:1:2 in terms of atomic ratio. If this is removed, a single phase of the target compound cannot be obtained. This mixture is stored in the air, in an oxidizing atmosphere, or
600℃ in a reducing atmosphere where Lu and Ga are not reduced from the trivalent ion state and Zn from the divalent ion state.
Heat under the above conditions. Heating time is several hours or more. There are no restrictions on the rate of temperature increase during heating. After heating, it can be rapidly cooled, or it can be rapidly drawn out into the atmosphere. The obtained LuGaZn 2 O 5 compound powder was colorless and was found to have a crystal structure by powder X-ray diffraction. The crystal structure was found to be layered, consisting of 1.5 layers of LuO, 2.5 layers of (Ga, Zn)O, and a stack of ZnO layers. Example Lutetium oxide (Lu 2 O 3 ) with a purity of 99.99% or more
Powder, gallium oxide (Ga 2 O 3 ) with a purity of over 99.99%
Powder and reagent-grade zinc oxide (ZnO) powder were weighed at a molar ratio of 1:1:4, ethanol was added in an agate mortar, and the mixture was mixed for about 30 minutes to form a fine powder with an average particle size of several μm. A mixture was obtained. The mixture was sealed in a platinum tube, placed in a tubular siliconite furnace set at 1300°C, and heated for 3 days, and then the sample was taken out of the furnace and rapidly cooled to room temperature. The obtained sample was a single phase of LuGaZn 2 O 5 , and the planar index (hkl), interplanar spacing (d p ), and relative reflection intensity (I%) were measured by powder X-ray diffraction. The results were as shown in Table-2. The lattice constants as a hexagonal crystal system were a=3.365±0.001 (Å) and c=22.05±0.01 (Å). The above lattice constants and the surface index (hkl) in Table 2
The calculated interplanar spacing (d c (Å)) was in excellent agreement with the actually measured interplanar spacing (d p (Å)). Effects of the Invention The present invention provides novel compounds useful as optical functional materials, semiconductor materials, and catalysts.
