Efficient oxide phosphors for light upconversion; green emission from Yb3+ and Ho3+ co-doped Ln2BaZnO5 (Ln = Y, Gd)

The optical properties of Yb3+ and Ho3+ co-doped Y2BaZnO5, synthesized by solid-state reactions, are investigated in detail. Under 977 nm excitation ([similar]25 [times] 10-3 W mm-2), bright green upconversion emission is observed. Concentration dependence studies at room temperature show that relat...
