摘要
碳纳米粒子悬浮液具有良好的光限幅性质,是一种优良的宽波段光限幅材料。通过热传导方程和米氏散射理论建立了微气泡半径与入射光能量、碳纳米粒子悬浮液散射系数和透过率的理论模型。采用Matlab数值模拟了散射系数随微气泡尺寸因子的变化关系,碳纳米粒子悬浮液光限幅性能随入射光能量的变化规律。研究了气泡尺寸因子、入射激光能量以及波长对碳纳米粒子悬浮液光限幅特性的影响。研究发现当激光能量达到一定值时,微气泡的半径保持恒定,不再随入射激光能量的增加而增加。微气泡尺寸的增大对碳纳米粒子悬浮液的透过率有着显著的影响。同时,碳纳米粒子悬浮液对不同入射光波长和光能表现出不同的光限幅性能。研究结果为实验研究提供了理论指导。
Carbon nanoparticle suspension has a good optical limiting properties,which is an excellent broadband optical limiting material.The relationship between micro-bubble radius and the incident light energy,theoretical mode of carbon nanoparticles suspension scattering coefficient and transmission ratio are established by heat conduction equations and Mie scattering theory.The variation of the scattering coefficient with the micro bubble size factor and optical limiting properties' change law with the incident light energy's change are simulated by matlab.The effects of bubble size factor,incident laser energy and wavelength on the optical limiting properties of carbon nanoparticles are investigated.It shows that when the laser energy reaches a certain value,the radius of the micro bubbles is kept constant,and no longer increases with the increase of the laser energy.The increase of micro bubble size has a significant effect on the transmittance of the suspensions of carbon nanoparticles.Meanwhile,carbon nanoparticle suspension has different optical limiting properties for different incident light wavelengths and light energy.The research results provide theoretical guidance for the experimental study.
