Annealing effects of Ga@d2O@d3-ZnO core-shell heteronanowires

Annealing effects of Ga@d2O@d3-ZnO core-shell heteronanowires

We prepared ZnO-coated Ga@d2O@d3 nanowires and investigated changes in the morphological, structural, and photoluminescence (PL) characteristics resulting from application of a thermal annealing process. With the thermal annealing at 800@uoC, defect-associated PL peaks (2.2 and 2.6eV) have been inte...

description We prepared ZnO-coated Ga@d2O@d3 nanowires and investigated changes in the morphological, structural, and photoluminescence (PL) characteristics resulting from application of a thermal annealing process. With the thermal annealing at 800@uoC, defect-associated PL peaks (2.2 and 2.6eV) have been intensified with respect to the UV peak, and a new 2.8eV-peak has been generated. Possible emission mechanisms are also discussed.
