Name：Nano zinc oxide rod-like sheet mixture
Product Overview
Zinc oxide is an important II-VI group oxide semiconductor material, with three different crystal structures: tetragonal rock salt structure, wurtzite structure, and sphalerite structure. Generally speaking, under natural conditions, the hexagonal wurtzite structure is the main crystalline state, belonging to the hexagonal crystal system with space group P63mc, and is the thermodynamically stable phase of zinc oxide. At room temperature, its rock salt structure is a metastable state formed by the transformation of zinc oxide from wurtzite under high pressure (approximately 9Gpa), with a volume reduction of about 17%. When the pressure returns to normal, the rock salt structure does not immediately return to the hexagonal wurtzite structure [5]. Zinc oxide with sphalerite structure requires higher pressure to obtain. The thermodynamic stability phase is a wurtzite structure belonging to the hexagonal crystal system. Zinc atoms and oxygen atoms are arranged in a hexagonal close packed manner, with all zinc atoms located within the tetrahedral gaps formed by four adjacent oxygen atoms. However, only half of the oxygen tetrahedral gaps are present, and the arrangement of oxygen atoms is similar to that of zinc atoms. The preparation methods of zinc oxide nanorods include hydrothermal method, ultrasonic method, microwave method, and chemical deposition method. XFI18 zinc oxide nanorods are prepared by thermal evaporation method and have a high aspect ratio, which makes them excellent in optoelectronic performance.
