MnF2SiO2 Transport Properties of Quasiperiodic Photonic Crystals for Potential Catalytic Applications

Abstract EN

Magnetically recyclable materials should be ideal support in photocatalytic system because they permit the photocatalysts to be recovered rapidly and efficiently by applying an external magnetic field such as, MnF2.

In this paper, MnF2 and SiO2 layers constitute a one-dimensional quasiperiodic photonic crystal according to Fibonacci.

When the electromagnetic wave irradiates obliquely, the transmission peak moves to higher frequency direction with the angle increasing.

Both the number of transmission peaks and the transmission peaks of double-forked structure increase with the increase of structural progression.

We also found that the polarization of electromagnetic waves has influence on the transmission properties; TM wave transmission peak half wide is significantly greater than TE wave transmission peak half wide.

The band gap near antiferromagnetic (AF) resonance frequency becomes narrow as the intensity of the applied static magnetic field increases.

The as-prepared photonic crystal has tremendous potential practical use to eliminate organic pollutants from wastewater.
