|Title:||Luminescence from ascorbate-stabilized Er2O3 Nanoparticles|
Chiu Zarate, R.
Perez Ladron de Guevara, H.
|Abstract:||We report a novel method to stabilize Er2O3 nanoparticles with ascorbate ligands. The Er2O3 nanoparticles had strong green and red emissions with sharp and well defined emission peaks. In addition, less intense UV, blue and NIR emissions were also detected. The luminescence was recorded under dynamical pumping at 525nm, 805nm, and 975nm. An enhancement of the red emission is observed when the nanoparticles were pumped at 975nm. We suggest this was due to the absorption cross sections involved in the different pumping schemes. © 2015 Photonics Society of Poland.|
