Effect of Er and Yb Doping Concentration on the Luminescent Properties of Y2O2S:Yb, Er Phosphors

Abstract:

Article Preview

Up-conversion luminescent materials of Y2O2S:Yb, Er with different doping concentrations of Er3+ ion (1 mol%–6 mol%) and Yb3+ ion (4 mol%–16 mol%) were prepared by flux method. As Yb3+ doping concentration was fixed at 8 mol%, when Er3+ doping concentration was 2 mol%, the green and red up-conversion luminescent intensity reached the maximum. As Er3+ doping concentration was fixed at 2 mol%, when Yb3+ doping concentration was 4 mol%, the green and red emission intensity reached the maximum. The up-conversion luminescent colours were adjustable.
