Abstract

The invention relates to a nano particle precise order assembling method. Firstly, an optical etching method is used for conducting surface etching on a hardness board, a columnar array structure is obtained with order arrangement is obtained from the surface of the hardness board, the board which is of the columnar array structure and provided with the order arrangement on the surface and a board with the flat surface serve as a lower base and an upper base respectively, suspension liquid containing nano particles is filled between the board which serves as the lower base, is provided with the order arrangement on the surface and is of the columnar array structure and the board which serves as the upper base and is provided with the flat surface to form a sandwich interlayer structure, after solvent in the suspension liquid is volatilized, the upper base and the lower base are separated, and a nano particle array which is precisely assembled is obtained from the board with the flat surface. The nano particle array prepared by the nano particle precise order assembling method can achieve precise assembling of the nano particles at the specific position, and in addition, the prepared nano particle array has potential application value in microelectronic circuits, optical elements and magnetic devices.
