摘要

低温条件下用不同剂量的MeV Au离子束

轰击由二氧化硅微球自组装形成的光子晶体。辐照前后

光子晶体的光学性质发生了明显的变化。主要体现为其光学反射谱的变化:反射带变宽并且中心位置向短波方向发生了迁移;另外

随着辐照剂量的上升

这些变化愈加明显。通过光谱曲线拟合分析

并结合SEM照片

文中给出了相应的理论解释。本文为用离子束改变光子晶体结构

从而获得具有特定光学反射带的光子晶体提供了实验和理论依据。

Abstract

Self-assembled silica PC (photonic crystals) were bombarded by 6 MeV Au ions to different doses at LN temperature. Reflection spectra of the irradiated PC exhibited the following transformations: the centre of reflection band shifted toward short wavelength

and the bandwidth was broadened. Moreover

the shift and broadening of reflection band increased with the dose. By fitting- analysis of the spectra

combining the SEM imaging

we came up with an explanation

which attributes optical transformations of PC to the structural changes induced by ion irradiation. This work could be of help for modifying the PC structure to achieve specific optical properties.
