Color-tunable up-conversion emission in Y(2)O(3):Yb(3+), Er(3+) nanoparticles prepared by polymer complex solution method

ABSTRACT: Powders of Y(2)O(3) co-doped with Yb(3+) and Er(3+) composed of well-crystallized nanoparticles (30 to 50 nm in diameter) with no adsorbed ligand species on their surface are prepared by polymer complex solution method. These powders exhibit up-conversion emission upon 978-nm excitation wi...

description ABSTRACT: Powders of Y(2)O(3) co-doped with Yb(3+) and Er(3+) composed of well-crystallized nanoparticles (30 to 50 nm in diameter) with no adsorbed ligand species on their surface are prepared by polymer complex solution method. These powders exhibit up-conversion emission upon 978-nm excitation with a color that can be tuned from green to red by changing the Yb(3+)/Er(3+) concentration ratio. The mechanism underlying up-conversion color changes is presented along with material structural and optical properties. PACS: 42.70.-a, 78.55.Hx, 78.60.-b
