Abstract

The invention belongs to the field of luminescent materials, and discloses a preparation method of a ZnO nano-rod array. The preparation method comprises the following steps of: cleaning a substrate; preparing a ZnO seed layer precursor solution; preparing a ZnO seed layer; preparing the ZnO nano-rod array; and preparing adsorption metal nano-particles of the ZnO nano-rod array. For the ZnO nano-rod array provided by the invention, the metal nano-particles are introduced to the surface of each ZnO nano-rod, and the luminescent efficiency of the ZnO nano-rods is increased by using the surface plasma effect of the metal nano-particles so as to obtain the ZnO nano-rod array with excellent ultraviolet emission performance; meanwhile, the preparation method is simple in process, needs no expensive equipment, and is low in cost.

Description

technical field

[0001] The invention relates to the field of photoelectric materials, in particular to a method for preparing a ZnO nanorod array with nanometer metal particles adsorbed on the surface. Background technique

[0002] ZnO is a wide bandgap (Eg=3.4eV) direct bandgap semiconductor material with excellent piezoelectric, electrical and optical properties, and has been used to prepare gas sensors, ultrasonic oscillators, transparent electrodes for solar cells, etc. functional material devices. As a light-emitting material, ZnO is also widely used in light-emitting diodes, lasers, cathode ray luminescence and other fields, and has attracted widespread attention.

[0003] Since Yang et al. synthesized ZnO nanorod arrays on a sapphire substrate in 2001 and observed ultraviolet laser emission under optical pump excitation in room temperature environment (M.Huang, S.Mao, H.Feick, H.Yan, Y .Wu, H.Kind, E.Weber, R.Russo, P.Yang, Science 2001, 292, 1897), the study of the...
