Problems solved by technology

The group-type polymer template method is similar to the photolithography and etching process of semiconductor guide exposure. It uses the multi-layer structure and the difference in etching rate, so the transfer process is too complicated and the production cost is quite high, so it has no industrial application value.

Embodiment Construction

[0022] FIG. 1( a ) and FIG. 1( b ) illustrate the preparation method of the nano metal particles 16 of the present invention. In the preparation method of the present invention, a conductive substrate 12 is soaked in an electroplating solution 20 containing metal ions 22, and then an electroplating process (such as a cyclic potential electroplating process) is performed to reduce the metal ions 22 to form nano-metal particles 16 in the electroplating solution 20. on the conductive substrate 12 . Preferably, the size of the nano metal particles 16 is between 1 nm and 150 nm. The conductive substrate 12 may include indium tin oxide (ITO) with a lattice size ranging from 5 nm to 500 nm, the electroplating solution 20 may include nickel nitrate, nickel sulfate, or nickel chloride, and the nano-metal particles 16 It may be nickel metal particles. In addition, the electroplating solution 20 can also be magnetic metal ions such as iron ions or cobalt ions, and the nano-metal partic...

Abstract

The invention relates to a method of preparing nano-metal particles, which is characterized by soaking a conducting substrate into an electroplating solution which contains metal ions, and then an electroplating process is carried out to reduce the metal ions and form nano-metal particles on the conducting substrate. Second, the invention can utilize the nano-metal particles as catalyst so as to conduct a chemical vapor deposition technique and form carbon-nano tubes on the conducting substrate. After that, the invention can form a fluorescent substance on the carbon-nano tubes so as to form a luminous element. When a preset voltage is exerted between the conducting substrate and the fluorescent substance, the carbon-nano tubes on the conducting substrate then emit electrons due to the point discharge effect, so as to bombard the fluorescent substance to produce beam.

Description

technical field [0001] The present invention relates to a preparation method of nano-metal particles and a method for preparing carbon nanotubes and a method for preparing light-emitting elements thereof, in particular to a method for preparing nano-metal particles that reduce metal ions by using an electroplating process and a method for preparing carbon nanotubes The method and the preparation method of the light-emitting element thereof. Background technique [0002] According to different principles, researchers have developed many nano-metal particle array technologies, such as electron beam writing method, anodized aluminum template method, microcontact printing method and group-type polymer template method. [0003] Although the electron beam writing method (see: J.Mater.Res., Vol.16, p3246, 2001) can implant nano-metal particles with arbitrary precision, the writing process is quite time-consuming and is not suitable for efficiency and large-area batches Production ...
