A unique set of undoped and Er-doped ZnO nanorods that are grown by a hydrothermal method under exactly the same conditions in the form of 2D nanoarrays on the SiO2/ZnO substrate or in a free-standing form on random nucleation seeds in solution were investigated. Their optoelectronic properties are characterized by photo-, radio-, and cathodoluminescence in correlation with scanning electron microscopy, energy-dispersive X-ray spectroscopy, electron paramagnetic resonance spectroscopy, resonance Raman spectroscopy, and theoretical computing by using density functional theory. We demonstrate that erbium is incorporated at a regular zinc site in the 2D arrays and as additional nucleation seeds in the free-standing nanorods.
