Beschreibung
Zusammenfassung:	The invention discloses a method for improving surface plasmon resonance stability of copper nanoparticles, which is used for performing oxygen plasma irradiation on the copper nanoparticles so as to improve the surface plasmon resonance stability of the copper nanoparticles. According to the method, the oxygen plasma rapid oxidation technology is adopted, the shell layer grows from the surface of the copper nanoparticle, external air is prevented from entering the interior, and therefore the surface plasmon resonance stability of the copper nanoparticle is maintained, the effect is remarkable, efficiency is high, and operation is easy. 本发明公开了一种提高铜纳米颗粒表面等离激元共振稳定性的方法，是对铜纳米颗粒进行氧等离子体辐照，从而提高铜纳米颗粒的表面等离激元共振稳定性。本发明采取氧等离子体快速氧化技术，从铜纳米颗粒表面生长出壳层，阻止外部空气进入内部，从而维持铜纳米颗粒的表面等离激元共振稳定性，效果显著、效率高、操作简单。
