Embodiment 1

[0021] Example 1: Mix germanium dioxide, calcium acetate and distilled water accounting for 3% by weight of the water solvent and put them into a closed container. The total amount of germanium dioxide, calcium acetate and water solvent accounts for 60% of the closed container. It was then kept at a temperature of 180°C for 24 hours. Finally, a calcium germanate nanowire fluffy white product with a diameter of 20-100 nm and a length of more than 100 μm was obtained.

Embodiment 2

[0022] Example 2: Mix germanium dioxide, calcium chloride and distilled water accounting for 3% of the weight of the water solvent into a closed container, and the total amount of germanium dioxide, calcium chloride and water solvent accounts for 60% of the closed container. It was then kept at a temperature of 150°C for 24 hours. Finally, a calcium germanate nanowire fluffy white product with a diameter of 20-100 nm and a length of more than 100 μm was obtained.

Embodiment 3

[0023] Embodiment 3, after mixing germanium dioxide, calcium nitrate and distilled water accounting for 3% by weight of the water solvent, put them into a closed container, the total amount of germanium dioxide, calcium nitrate and water solvent accounts for 60% of the closed container. It was then kept at a temperature of 180°C for 12 hours. Finally, a calcium germanate nanowire fluffy white product with a diameter of 20-100 nm and a length of more than 100 μm was obtained.

Abstract

The invention provides a calcium germinate nanowire and a preparation method thereof, and belongs to the technical field of nano material preparation. The calcium germinate nanowire provided by the invention is prepared from monocrystalline calcium germinate with the diameter of between 20 to 100nm and the length of more than 100 mu m. In the preparation method, different calcium sources and germanium dioxide are taken as raw materials, and water is taken as a solvent, wherein the calcium sources are calcium acetate, calcium chloride or nitrate of lime; a molar ratio of calcium to germanium in the raw materials is 2:1; the preparation method comprises the following steps of: putting the germanium dioxide and the calcium-containing raw material into a stirrer, and adding the water and stirring; and placing mixed solution obtained after stirring into a sealed container, and then preserving the heat for 1 to 24 hours at the temperature of between 100 and 200 DEG C to obtain a white fluffy product, namely the calcium germinate nanowire. In the invention, the nontoxic germanium dioxide and the different calcium sources are used, and the water is taken as the solvent, so that the raw materials and the preparation process do not pollute the environment, and the preparation method accords with a development direction of the modern industry with the environmental-friendly requirement, and can realize environmental-friendly mass preparation for the calcium germinate nanowire.

Description

Technical field: [0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a calcium germanate nanowire and a preparation method thereof. Background technique: [0002] One-dimensional inorganic nanomaterials are important structural units of nano-optical devices, nano-sensor devices, electronic devices, and optoelectronic devices in the future, and have good development prospects in the field of basic research and applied research on low-dimensional nanomaterials. [0003] Calcium germanate is an important ternary compound, which has good optical properties and spintronic properties, and has good application prospects in the fields of optics and transistors. By preparing bulk calcium germanate into one-dimensional calcium germanate nanomaterials, such as calcium germanate nanowires, novel properties that calcium germanate bulk materials do not have can appear, such as quantum confinement effect, enhancement of photolumines...
