摘要

采用溶剂热和离子交换两步实验法,以YVO₄为无机基质,2-噻吩甲酰三氟丙酮(TTA)为有机配体,构建了具有核壳结构的YVO₄∶Eu³⁺@YVO₄∶Eu³⁺-TTA稀土杂化发光材料,研究了其高效的发光性能和内部的能量传递机制。结果表明,在621nm的监控波长下,YVO₄∶Eu³⁺@YVO₄∶Eu³⁺-TTA稀土杂化发光材料在280～420nm范围内有两个很强的吸收峰(即V-O峰和TTA特征吸收峰)。YVO₄基质通过交换作用能量传递,而TTA有机配体通过分子内能量传递,可将吸收的紫外光能量有效地传递给Eu³⁺,从而实现了Eu³⁺更高效的可见光(红光)发射。

Abstract

Using YVO₄ as the inorganic substrate and 2-Thiophenoyltrifluoroacetone (TTA) as the organic ligand,we constructed YVO₄∶Eu³⁺@YVO₄∶Eu³⁺-TTA rare earth hybrid luminescent materials with core-shell structure by solvothermal and ion-exchange experiments.The efficient luminescence performance and internal energy transfer mechanism were investigated.Experimental results showed that YVO₄∶Eu³⁺@YVO₄∶Eu³⁺-TTA rare earth hybrid luminescent materials had two strong absorption peaks (Namely,V-O peak and TTA characteristic absorption peak) in the range of 280～420nm at the monitoring wavelength of 621nm.YVO₄ matrix transferred energy through exchange interactions,while TTA organic ligand transferred the absorbed ultraviolet energy to Eu³⁺ effectively through intramolecular energy transfer,thus achieving more efficient visible (red) light emission from Eu³⁺.
