| 摘 要： | 采用Mie理论,对球形纳米金属颗粒进行数值计算,研究了金属纳米颗粒在发生表面等离激元共振时表现出的散射效应.改变金属材料类型或者颗粒尺寸大小,金属纳米球的散射效率均发生不同程度的变化.这一现象表明:金属纳米颗粒的散射效应受材料类型和尺寸大小的影响显著.计算结果表明,半径为100nm的Ag纳米颗粒在发生表面等离激元共振时,散射效率最高,吸收效应最弱.

| Abstract: | The scattering properties of metal nanoparticles when excited into surface plasmon resonance are numerically studied.When different materials are chosen or the sizes of the particles are adjusted,their scattering properties will change.It is demonstrated that the scattering effect of metal nanoparticle is dependent on the material and size of the particle.Compared with other materials,the Ag nanoparticle with 100 nm radius presents a highest scattering efficiency and lowest absorption efficiency. |
