理论上采用转移矩阵法研究了具有P3OT/AlN多层膜结构的一维半导体-有机物型光子晶体的光学特性.计算结果表明:由厚度分别为30,30nm的P3OT,AlN薄膜组成的多层膜结构,在中心波段为275nm处有一不完全的光子带隙存在,反射率最高可达98%;而且可以通过调整薄膜厚度、填充比等参数对光子带隙的位置、反射强度进行调制.因此,这种一维半导体-有机物型光子晶体对在紫外波段获得具有一定功能的光子晶体具有重要的指导意义.
The optical properties of a one-dimensional semiconductor-organic photonic crystal with P3OT / AlN multilayered structure have been theoretically studied by using transfer matrix method. The calculated results show that the multilayer films consisting of P3OT and AlN thin films with thickness of 30 and 30 nm, respectively Structure with an incomplete photonic bandgap at 275 nm in the central wavelength range and a maximum reflectivity of up to 98%, and the position and reflection intensity of photonic bandgap can be modulated by adjusting parameters such as film thickness and fill ratio, This one-dimensional semiconductor-organic type photonic crystal has an important guiding significance for obtaining a certain function photonic crystal in the ultraviolet wavelength range.
