NIR-triggered upconversion and sensitized NIR-emission in Yb-based Eosin Y lake doped latex nanoparticles

NIR-triggered upconversion and sensitized NIR-emission in Yb-based Eosin Y lake doped latex nanoparticles

Here, Yb-based Eosin Y lakes (EOS-Yb) have been encapsulated in organic nanoparticles (NPs) by microemulsion radical polymerization of methacrylate-based copolymers. These photoactive EOS-Yb NPs emit in the visible and near infrared (NIR) upon excitation at 530 nm and can also display NIR-to-visible...

description Here, Yb-based Eosin Y lakes (EOS-Yb) have been encapsulated in organic nanoparticles (NPs) by microemulsion radical polymerization of methacrylate-based copolymers. These photoactive EOS-Yb NPs emit in the visible and near infrared (NIR) upon excitation at 530 nm and can also display NIR-to-visible upconversion emission upon excitation at 980 nm. Yb-based Eosin Y lakes (EOS-Yb) doped latex nanoparticles can display either NIR-triggered upconversion or sensitized NIR-emission upon visible excitation.
