Problems solved by technology

Although this method can prepare tin-doped indium oxide nanopowders with different particle sizes, the process is relatively complicated, the process is not easy to control, and the morphology of the powder cannot be effectively controlled.
And also there are two deficiencies: the one is to use a large amount of chemical reagents, such as alcohol, alkali, acid, etc., which not only increases the production cost, but also causes harm and pollution to the operator and the enviro

Embodiment 1

[0032] Weigh 3.5 moles of indium chloride and dissolve it in 7 liters of deionized water to prepare a solution with a molar concentration of 0.5 mol / L. Then add 0.35 moles of tin chloride, so that the molar ratio of tin ions to indium metal ions is 0.1. After fully stirring and dissolving at room temperature, add 25% ammonia water dropwise to the solution pH=11 with an automatic titrator, and transfer the solution to In a 10L polytetrafluoroethylene or alkali corrosion-resistant metal-lined stainless steel reactor coated with anti-corrosion materials, the filling degree of the reactor is 70%, and the hydrothermal treatment is carried out at 260 degrees Celsius for 6 hours. The product is washed about 5 times with deionized water to remove acid radical ions and impurity ions, and dried at 100 degrees Celsius for 6-12 hours to obtain a single dispersed tin-doped indium oxide powder. It can be determined by TEM analysis that the particles in the tin-doped indium oxide powder have...

Abstract

The invention provides a preparation method of spherical tin-doped indium oxide nanopowder. The method comprises the steps: (1) weighing a water-soluble indium salt and dissolving the water-soluble indium salt in deionized water, adding a tin salt serving as a doping agent, and fully stirring at room temperature to obtain a mixture solution; (2) adding ammonia water or an ammonia salt into the mixture solution to regulate a pH value to be 9-11 to generate a precursor; (3) transferring the precursor into a reaction kettle, and carrying out hydrothermal synthesis reaction for 3-120 hours at the temperature of 260-360 DEG C to obtain a reaction product; and (4) cooling the reaction product in the reaction kettle to room temperature, and then cleaning the reaction product with the deionized water and drying, thereby obtaining the spherical tin-doped indium oxide nanopowder of nanometer particle diameter. The tin-doped indium oxide nanopowder prepared by using the method disclosed by the invention is spherical in appearance and has the average particle size of being 20-400nm.

Description

technical field [0001] The invention relates to the field of photoelectric functional materials, and more specifically relates to a hydrothermal synthesis method for preparing tin-doped indium oxide spherical nanopowder. Background technique [0002] Transparent conductive tin-doped indium oxide semiconductor materials have been widely used in many fields due to their special optical and electrical properties, such as liquid crystal displays (LCDs), plasma displays (PDPs), organic light-emitting diodes (OLEDs) and solar cells, etc. . In the family of transparent conductive oxides, tin-doped indium oxide is the most mature material in terms of technology development and application. As a transparent conductive n-type semiconductor material. Due to its stable chemical and mechanical properties and its transparent and conductive properties, no transparent conductive material that can replace it has yet been found. Those skilled in the art are still committed to researching n...
