Abstract

The invention provides a preparation method of a nanoparticle linear array resistor. The preparation method comprises the steps: a prepared sample is obtained; the prepared sample is put on a three-dimensional micro displacement platform; femtosecond pulse laser passes through an optical path system to transmit a quartz slide to be focused on the surface of a gold film; a PC controls the three-dimensional micro displacement platform to move in the directions of a Y axis and a Z axis; the gold film is subjected to ablation by the focused laser to form plasma spray in a constraint space; the spayed gold nanoparticles are received by the covered glass, and the gold nanoparticle linear array resistor is obtained on the glass surface; and the morphology features of the gold nanoparticle lineararray resistor are represented. The method is based on a femtosecond laser micro-nano processing platform and is combination with a laser induced backward transfer technology; by controlling femtosecond pulse laser energy density, scanning speed and processing number of branches, the linear array resistor formed by the gold nanoparticles is prepared; and the gold nanoparticle morphology features of different processing parameters are represented by a scanning electron microscope and an atomic force microscope.
