一般描述

此系列產(chǎn)品為PEG包覆上轉(zhuǎn)換納米顆粒，材料組成為NaYREF4 (RE:Yb, Er, Tm, Gd, Mn, Lu)，激發(fā)波長為975 nm。敏化離子為Yb3+，激活離子為Er3+或Tm3+。通過調(diào)節(jié)各離子摻雜濃度，產(chǎn)品在特定波長的發(fā)光已得到優(yōu)化。表面包覆的PEG使納米顆粒具有良好的親水性，可以直接分散在水介質(zhì)中。產(chǎn)品粒徑均一，發(fā)光量子效率高，光穩(wěn)定性好。

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
