正常分析此系列物料物料为PEG包裹上转化成纳米级级粉末,建筑材料主成为NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu),抑制光波光的波长为975 nm。敏化阳阴阳铁离子为Yb3+,系统激活阳阴阳铁离子为Er3+或Tm3+。使用调结各阳阴阳铁离子夹杂氧浓度,物料在某一光波光的波长的会亮已拥有改善。表面层包裹的PEG使纳米级级粉末有着比较好的亲水性树脂,是可以可以直接减少在水媒质中。物料比表面积均一,会亮量子有工作效率更高,光可靠性好。This series of products contains PEG coated NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu) UCNs with optimal excitation wavelength at 975 nm. The sensitizer is Yb3+, and the activator is Er3+ or Tm3+. The doping concentrations are optimized, leading to strong upconverted emissions at specific wavelengths.The nanoparticles are highly hydrophilic due to the PEG coating.The UCNs are of high quantum efficiency and very photostable
