Abstract |
Upconversion nanoparticles (UCNPs) are a unique type of photoluminescence in which lower-energy excitation is converted into higher-energy emission via multi-photon absorption processes. In this work, a facile synthesis of Yb3+/Tm3+ doped NaYF4 UCNPs coated with polyacrylic acid (PAA) was accomplished by the one-step hydrothermal method. Then polyepinephrine (PEP) formed on the UCNPs via self-polymerization of epinephrine. After polymer coated UCNPs showed enhancement of upconversion luminescence (UCL), and optimize condition was found. The successful synthesis of NaYF4:Yb3+/Tm3+@PEP was used for optosensing of the Fe3+ ion. In detail, luminescence properties and morphology were discussed. From the obtained results, could be concluded that NaYF4:Yb3+/Tm3+@PEP was successfully synthesized by the one-step hydrothermal approach, which is detected Fe3+ ion in aqueous system with high selective, sensitive, and simple. Furthermore, the NaYF4:Yb3+/Tm3+@PEP showed relatively high cell viability. The high-quality of the synthesized UCNPs have prominent potential applications for optical nanodevices, bioimaging, and bioanalytic sensing. |
