In this work, we report the synthesis of Y 2 O 3 :Er 3+ , Y 2 O 3 :Yb 3+ and Y 2 O 3 :Er 3+ ,Yb 3+ nanophosphors by the combustion synthesis method using urea as fuel. The doping agents were incorporated in the form of erbium nitrate and ytterbium nitrate. X‐Ray diffraction (XRD) patterns revealed that the synthesized particles have a body‐centered cubic structure with space group Ia‐3. The photoluminescence (PL) properties were investigated after UV and infrared irradiation at room temperature. A strong characteristic emission of Er 3+ and Yb 3+ ions was identified, and the influence of doping concentration on the PL properties was systematically studied. Energy transfer from Yb 3+ to Er 3+ ions was observed in Y 2 O 3 nanophosphors. The obtained result may be useful in potential applications such as bioimaging. Copyright © 2015 John Wiley & Sons, Ltd.
