基于光子晶体的物质的量浓度测量研究

采用平面波展开法模拟graphite格子二维光子晶体的禁带结构,研究了三种溶液温度和质量摩尔浓度分别对光子带隙的影响。其中半乳糖、木糖和核糖溶液分别为graphite格子二维光子晶体的空气孔介质材料。结果表明,当质量摩尔浓度恒定而温度变化,光子带隙随其发生变化;而当溶液温度恒定时,光子带隙随溶液质量摩尔浓度发生变化。较高质量摩尔浓度和较高温度的溶液更容易形成光子带隙。在某些情况下,核糖溶液比半乳糖和木糖溶液更容易实现光子带隙。

Applied Research Of Molarity Detection Technology In Photonic Crystals

The plane wave expansion method is used to simulate the band gap of two-dimensional photonic crystal with graph-ite lattice,to study the effect of temperature and molarity of three kinds of solution on the photonic band gap. Where galactose, xy-lose and ribose solution were air holes dielectric materials of two-dimensional photonic crystal with graphite lattice .The results show that with a constant molarity ,the photonic band gap changes with the temperature of the solution .Similarly, for a given temperature of the solution, the photonic band gap changes with the molarity of the solution. . In some cases, ribose solution was easier to achieve the photonic band gap xylose and galactose solution .
