摘要

本文报道了Ho3+/Yb3+共掺杂Sr2LaF7荧光粉的合成及其上转换发光性能。用湿化学法合成了它。采用XRD、SEM、HRTEM等分析方法研究了所制荧光粉的结构和形貌。在980 nm激光激发下，Sr2LaF7: Ho3+/Yb3+纳米荧光粉在可见光到近红外范围内的光致发光现象。因此，它在542 nm处表现出强烈的绿色上转换，在645 nm和653 nm处分别观察到双态红色发射带。随着Ho3+离子浓度的增加，发射强度增强。因此，纳米晶Sr2LaF7: Ho3+/Yb3+是一种很有前景的生物成像应用宿主。

Structural and Optical Properties of NIR Laser Excited Ho3+/Yb3+ Doped Sr2LaF7 UC Phosphor

This article reported the synthesis and upconversion luminescence properties of Ho³⁺/Yb³⁺ co-doped Sr₂LaF₇ phosphors. It has been synthesized by the wet chemical method. The structural and morphological properties of the prepared phosphor were studied by XRD, SEM, and HRTEM analysis. UCL of Sr₂LaF₇: Ho³⁺/Yb³⁺ nanophosphors was observed in the visible to NIR range under 980-nm laser excitation. Thus, it exhibits intense green upconversion at 542 nm, and doublet red emission bands were observed at 645 and 653 nm, respectively. The emission intensities were enhanced by increasing the concentration of Ho³⁺ ions. Hence, nanocrystalline Sr₂LaF₇: Ho³⁺/Yb³⁺ is a promising host for bioimaging applications.
