摘要

本文借助外延生长及离子掺杂技术, 基于NaYbF₄:2%Er³⁺微米晶体构建了多种不同的核壳微米盘, 通过降低材料的表面猝灭效应及增强离子间的能量传递效应, 实现了NaYbF₄:2%Er³⁺微米晶体上转换红光发射的增强. 研究结果表明: 在980 nm近红外激光激发下, 构建的NaYbF₄:2%Er³⁺@NaYbF₄@NaYF₄核-壳-壳微米盘的上转换红光发射强度相比于NaYbF₄:2%Er³⁺微米盘增强了4.6倍, 红绿比由6.3提高至8.1. 当少量Ho³⁺离子引入到NaYbF₄:2%Er³⁺@NaYbF₄:2%Ho³⁺@NaYF₄核-壳-壳微米盘时, Er³⁺离子与Ho³⁺离子间相互作用的发生使其上转换红光发射强度相比于NaYbF₄:2%Er³⁺微米盘增强了近6.7倍, 且红绿比更是提高到9.4. 通过对不同核壳微米盘光谱特性和发光动力学的研究, 表明Er³⁺离子的红光发射增强主要源自于不同核壳结构中Yb³⁺离子的高效的能量传递有效促进了Er³⁺离子间的交叉弛豫、Er³⁺和Yb³⁺离子间反向能量传递及Ho³⁺离子向Er³⁺离子间的能量传递的发生, 进而提高了红光发射能级的粒子数布居. 其研究可为构建具有高效红光发射的上转换微纳晶体提供新途径.

Abstract

The construction of core-shell structure can effectively reduce the quenching effect on the surface of material and regulate ion-ion interaction, which has become one of the effective ways to enhance and regulate the spectral characteristics of rare-earth upconversion luminescent materials. In this paper, a variety of NaYbF₄: 2%Er³⁺ micron core-shell structures are constructed with the help of epitaxial growth technology, effectively improving the red up-conversion emission of Er³⁺ ions. The prepared microcrystals with core-shell structures are of hexagonal phase microdisks, and their sizes are relatively uniform. In order to better obtain the material spectral data, a confocal microscopic spectroscopy is used to study spectral properties. Under 980 nm near-infrared laser excitation, the red emission intensity of single NaYbF₄:2%Er³⁺@NaYbF₄@NaYF₄ core-shell-shell microdisk is 4.6 times higher than that of NaYbF₄:2%Er³⁺ micron disk, and the red-to-green ratio increases from 6.3 to 8.1. Meanwhile, Ho³⁺ ions are introduced into the NaYbF₄:2%Er³⁺@NaYbF₄: 2%Ho³⁺ @NaYF₄ core-shell-shell microdisk, and the red emission intensity is nearly 6.7 times higher than that of single NaYbF₄: 2%Er³⁺ microdisk, and the red-to-green ratio increases from 6.3 to 9.4 through the interaction between ions. The microcrystal spectral characteristics and luminescence kinetics of different core-shell structures are studied, showing that the red emission enhancement of Er³⁺ ions is mainly derived from the construction of different core-shell structures, which can effectively enhance the cross-relaxation between Er³⁺ ions, the energy back transfer between Yb³⁺ and Er³⁺ ions, and the energy transfer from Ho³⁺ ions to Er³⁺ ions. The micron core-shell structures with efficient red emission in this study has great application prospects in the fields of luminescence, anti-counterfeiting and optoelectronic devices.
