Abstract

Nanoparticles of YVO₄ doped with Yb³⁺ and Er³⁺ ions, which exhibit upconversion luminescence upon cw laser excitation at 980 nm, are synthesized according to the familiar hydrothermal procedure. Physical and structural features of intermediate products obtained at different technological stages of creating upconversion nanoparticles are established via electron microscopy, Raman spectroscopy, and luminescence microscopy.

合成条件对上转换纳米粒子YVO 4：Yb，Er发光性质的影响

摘要

根据熟悉的水热程序，合成了掺有Yb ³⁺和Er ³⁺离子的YVO ₄纳米粒子，该粒子在980 nm的连续激光激发下表现出上转换发光。通过电子显微镜，拉曼光谱和发光显微镜确定在产生上转换纳米颗粒的不同技术阶段获得的中间产物的物理和结构特征。
