Morphology, Luminescence, and Optical Properties of Tb‐ and Li‐Codoped ZnO Elongated Nano‐ and Microstructures

A variety of morphologies of ZnO elongated nano- and microstructures doped with Li and Tb are obtained by a vapor–solid method. The amount of Tb incorporated depends on the morphology which is controlled by the amount of Li in the initial mixture and the growth conditions. X-ray diffraction and Rama...
