Photoluminescence transient study of surface defects in ZnO nanorods grown by chemical bath deposition

E. G. Barbagiovanni, V. Strano, G. Franzò +2

Two deep level defects (2.25 and 2.03 eV) associated with oxygen vacancies (V${}_o$) were identified in ZnO nanorods (NRs) grown by low cost chemical bath deposition. A transient beh…
