Tuning from green to red the upconversion emission of Y2O3:Er3+–Yb3+ nanophosphors
In this work, the structural, morphological and luminescent properties of Y 2 O 3 nanophosphors doped with Er 3+ (1 mol%) and different Yb 3+ concentrations (2–12 mol%) have been studied. Those nanophosphors were synthesized using a simple hydrothermal method. XRD analysis indicates that all the sam...
