Original Abstract

Lanthanide-doped photon-upconversion nanoparticles (UCNPs) are a new type of luminescent nanomaterials, the most commonly composed of NaYF4 nanocrystals doped with Er3+ and Yb3+. UCNPs have become widely used as luminescent labels because of their unique optical properties, which could lead to the replacement of traditional organic dyes and quantum dots. However, analogously to other classes of nanomaterials, UCNPs may eventually find their way into the environment. Because environmental organisms may come into contact with discarded UCNP-containing products, it is important to evaluate the possible environmental risks of UCNPs. In the present study, radish (Raphanus sativus L.) and common duckweed (Lemna minor L.) were treated with an aqueous dispersion of carboxylated silica-coated photon-upconversion nanoparticles containing rare-earth elements (Y, Yb, and Er).
