异质结构—NaGdF4:Yb,Er纳米棒负载在金属有机框架上以调节上转换光致发光
The heterostructure NaGdF4:Yb,Er nanorods loaded on metal-organic frameworks for tuning upconversion photoluminescence
摘要
Abstract
Multi-component heterostructure nanocomposites can not only inherit the original properties of eachcomponent,but also induce new chemical and electronic properties through the interaction between the compo-nents. The heterostructure zeolitic imidazolate framework/NaGdF4:Yb,Er(ZIF-67/NaGdF4:Yb,Er)was pre-pared by a stepwise synthesis strategy. And it avoided agglomeration and quenching of upconversion(UC) nanoparticles,and displayed better stability. In the heterostructure nanocomposites,ZIF-67 is employed as an en-ergy transmission platform under 980 nm excitation. Compared to pure NaGdF4:Yb,Er nanorods,the UC photo-luminescence of heterostructure ZIF-67/NaGdF4:Yb,Er is tuned from green to red owing to the synergistic effect of each component.关键词
