水分散性发红光Mn2+掺杂NaYF4∶Yb3+/Er3+上转换纳米粒子的合成
Synthesis of Red Luminescent Mn2+ Doped NaYF4∶Yb3+/Er3+ Nanoparticles Modified with Triton-Phosphate
摘要
Abstract
Mn 2 + doped-NaYF4∶Yb3+/Er3+ nanoparticles are synthesi2ed by one-step hydrothermal method using rare-earth nitrate as raw materials,and then the hydrophobic nanoparticles are transferred into water dispersible nanoparticles through the ligand-exchange method using triton-phosphateas as the hydrophilic ligand.The samples are characterized with transmission electron microscopy (TEM),dynamic light scattering (DLS),X-ray diffraction (XRD),fluorescence spectrophotometer,Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analyzer (TCA).The results reveal that the average size of triton-phosphate modified Mn2+ doped-NaYF4 ∶Yb3+/Er3+ nanoparticles are about 19.54 nm and exhibit good water dispensability.关键词
