含不同纳米银纳米粒子半径的纳米复合材料缺陷层的一维TiO 2 / SiO 2周期性层在主体液晶中增强传感性能的理论研究

在本文中，我们使用Maxwell-Garnett模型从理论上研究了具有不同半径的银纳米颗粒的液晶（LC）纳米复合材料（NC）层的有效介电常数。包含缺陷NC层（TiO 2 | SiO 2）3 | NC |（TiO 2 | SiO 2）3的TiO 2 / SiO 2介电材料的一维周期性结构（1DPS）的光学特性。使用众所周知的转移矩阵方法（TMM）在理论上研究了银纳米颗粒。## IMG ##的NC的有效介电常数[http://ej.iop.org/images/1402-4896/95/6/065507/psab82c5ieqn1.gif] {$ \ phi $} = 0°和90°由于纳米银颗粒的大小会影响表面等离振子共振（SPR），因此可以通过改变纳米颗粒的大小来计算LC的取向角。
