Effects of rare-earth (Er, La and Yb) doping on morphology and structure properties of ZnO nanostructures prepared by wet chemical method

Study of far infrared optical properties and, photocatalytic activity of ZnO/ZnS hetero-nanocomposite structure

“…36-1451), indicating that the as prepared nanostructured ZnO is crystalline and of high purity. 7,20 However, when synthesis was carried out in the presence of Na 2 S, the intensity of the diffraction peaks decreased signicantly and new ones belonging to the cubic sphalerite ZnS (JCPDS le no. 05-0566) appeared in the ZnO/ZnS nanocomposite sample.…”

Some physical investigations on hexagonal-shaped nanorods of lanthanum-doped ZnO

“…Similarly, Zamiri et al [20] doped ZnO by rare-earth ions (Er 3+ , La 3+ and Yb 3+ ) and found also that La 3+ ion cannot be incorporated into ZnO crystal.…”

“…Zamiri et al [20] also related the possible reason for the decrease in optical band gap to the change in defect concentration.…”

“…Recently, trivalent rare-earth ions such as Ce 3+ , Er 3+ , La 3+ and Yb 3+ doped semiconductors have attached much attention because their optical proprieties and promising applications in opto-electronic devises [20].…”

Synthesis and Characterization of Gadolinium Doped Zinc Oxide Nanorods Thin Films

“…Ga, Al, and In can be used as ntype dopant in ZnO, have been generally recognized to influence the optical and also the electrical properties of the materials [2].Other elements of rare earth group, i.e. Ce, Er, Eu, La, Tb, Tm, Yb, and Dy as p-type dopant to ZnO, have also attracted significant attention among the community due to their unique optical properties which give to intense emission peaks in the visible and near infrared range [3].Hence, the electrical conductivity, type of conduction and band gap range, including the magnetic characteristics of the nanomaterial can be manipulated through doping. Therefore, doping effect can enhance the present properties of ZnO and provides space for new applications possible.…”
