Abstract
The development of an easily upscalable method for the preparation of nanosized phosphors is reported, which comprises a simplified precipitation method for the synthesis of lanthanide (Ln)-doped Y2O3 nanoparticles (NPs). Co-doping the Y2O3 NPs with Tb3+ and Eu3+ led to a gradient of the emission color, this adjustment is very important for applications. The influence of different synthesis parameters on the mean particle size and the size distribution was unravelled and the toxicity of aminosilane functionalized and neat NPs was investigated.

Keywords: Y2O3 : Eu3+,Tb3+, Nanoparticles, Luminescence, Toxicity, Chemical precipitation.
