Site-selective laser spectroscopy and defect configurations of the Nd3+-Li+ centres in ZnO powders

Near-infrared emission in the 885–915 nm region was observed for two distinct Nd3+ centres that co-exist in hexagonal wurtzite ZnO:1 mol%Nd3+:10 mol%Li+ powders. The powder samples were prepared by sintering in air at 950 °C and the emission, attributed to the 4F3/2 → 4I9/2 transitions of Nd3+ ions,...
