Photoluminescence properties of β-SiAlON:Yb2+, a novel green-emitting phosphor for white light-emitting diodes

We have synthesized Yb2+-activated Si6−zAlzOzN8−z (0.05≤z≤2.3, 0.03 mol% ≤Yb2+≤0.7 mol%) green phosphors by solid-state reaction at 1900 °C for 2 h under a nitrogen pressure of 1.0 MPa. Phase purity, photoluminescence and its thermal quenching were investigated. A single phase was obtained for all v...
