Enhanced radioluminescence of yttrium pyrosilicate nanoparticles via rare earth multiplex doping

https://doi.org/10.1039/d2nr02417a

Zhang, Eric ; Bandera, Yuriy ; Dickey, Ashley ; Kolis, Joseph W. ; Foulger, Stephen H. ( August 2022 , Nanoscale)

A series of multi-doped yttrium pyrosilicate (YPS) nanoparticles were synthesized using a high temperature multi-composite reactor, and used to explore the radioluminescent properties that have potential for biological applications. The luminescent activators explored in this work were cerium, terbium, and europium. A series of mono-doped YPS nanoparticles were synthesized that have optical and X-ray luminescent properties that span the entire visible spectrum. Energy transfer experiments were investiagted to increase the photo- and X-ray luminescence of terbium and europium. Cerium was used as a sensitizer for terbium where X-ray luminescence was enhanced. Similar results were also obtained using cerium as a sensitizer and terbium as an energy bridge for europium. By leveraging different energy transfer mechanisms X-ray luminescence can be enhanced for YPS nanoparticles.

A high temperature approach to synthesize new optical and x-ray luminescent nanomaterials for biomedical applications

https://doi.org/10.1364/NOMA.2021.NoF2C.7

Zhang, Eric ; Dickey, Ashley ; Jones, Haley ; Foulger, Isabell ; Kolis, Joseph ; Foulger, Stephen ( January 2021 , OSA Advanced Photonics Congress 2021)

A high temperature reactor was developed to synthesize new scintillating nanoparticles that traditionally would sinter. Yttrium pyrosilicate nanoparticles were synthesized with optical properties suitable for x-ray biomedical applications.
