摘要

近年来，利用金属纳米结构表面等离激元共振提高半导体材料的发光效率取得了重要进展，但是相关结构体系面临着加工技术复杂、重复性差等缺点。本文报道了一种新型超薄、大面积、共振可调的平面双层纳米媒质用于增强量子点发光，其结构由深亚波长厚度、高吸收率特性的氧化铜(CuO)薄膜和金(Au)薄膜构成。实验结果显示，通过改变CuO薄膜厚度可以灵活调节CuO/Au双层堆栈结构的反射光谱，以其为基底旋涂CsPbBr

钙钛矿量子点后与裸石英旋涂CsPbBr

量子点参考样品相比实现了最大7倍的荧光发光增强。理论分析表明，荧光增强效应与强光学非对称法布里-珀罗薄膜干涉引起的高效光吸收和局域场增强导致的自发辐射速率加快相关。

Abstract

In recent years

great strides have been made in improving the luminous efficiency of semiconductor materials by using surface plasmon resonance. However

there still exist some disadvantages

such as sophisticated nanofabrication techniques

poor repeatability and so on. Here

a novel ultra-thin

large-area and tunable planar bilayer media is reported

which is composed of deep-subwavelength and high absorptive CuO thin films and Au substrate. Experimental results show that reflectance spectra of CuO/Au bilayer can be sensitively tuned by changing the thickness of CuO film. Compared with the bare quartz based reference sample

photoluminescence (PL) enhancement factor of quantum dots/CuO/Au trilayer can be achieved by up to 7 times. Theoretical analysis shows that PL enhancement effect is attributed to the high efficient absorption caused by Fabry-Perot thin film interference and the accelerated spontaneous emission rate resulted from local field enhancement.
