Synthesis, Characterization, and Photocatalysis of ZnO and Er‐Doped ZnO [PDF]

Journal of Nanomaterials, 2013
ZnO and Er‐doped ZnO with different molar ratios of Er/Zn were prepared using the homogeneous precipitation method. The photocatalysts prepared were characterized using scanning electron microscopy, transmission electron microscopy, X‐ray diffraction (XRD), UV‐vis spectroscopy, and photoluminescence spectroscopy.
