| Abstract: | Photoluminescence (PL) study of needle-like ZnO nanorods grown under standard and oxygen-rich conditions is presented. The yellow-orange band at ∼580 nm increases with excess oxygen during growth. Subsequent annealing in a reducing atmosphere shows the disappearance of this band. The yellow-orange emission is attributed to oxygen interstitials (Oi). |
