The invention discloses a method for preparing a nano material, in particular to a method for preparing an inorganic zinc oxide/tin oxide heterostructure material. According to a chemical vapor deposition method adopted by the invention, Sn powder and Zn powder, which serve as source materials, are placed in the front end of an alumina ship, a gold plated silicon substrate is placed at a certain distance from the source materials, the alumina ship is vacuumized and heated to a high temperature, then oxygen is introduced, the temperature is kept and the white product, namely ZnO/SnO2 heterostructure nanowire luminescent material, is formed on the substrate after cooling. The method provided by the invention has the advantages that: the process can be well controlled; the operation is easy; the cost is low; and the prepared product is very pure. The material prepared by the method can be widely used in the semiconductor industry.
