For the manufacture of high permeability Mn-Zn ferrite cores, the zinc loss from the surface of sintering cores causes poor yield rate of final products. This experiment uses the atmospherical protection to reduce the evaporation of zinc. The control of the oxygen partial pressure and flow rate precisely can reduce the zinc loss about 20% to 35%, but it is not enough to get a good distribution ...

The authors have demonstrated white light emission of rare earth (RE)-free Mn-doped SnO-ZnO-P(2)O(5) glass. The RE-free glass shows white light emission with a high value of quantum efficiency (QE) comparable to conventional crystalline phosphor. It is notable that the high QE value is attained for RE-free transparent glass, and the broad emission can be continuously tuned by both the amount of...

In the title hydrated mol-ecular salt, (C(7)H(7)N(2)S)(2)[Zn(C(8)H(8)O(5))(2)]·6H(2)O, which is isotypic with its Mn(II), Co(II) and Ni(II) analogues, the Zn(2+) ion lies on a crystallographic inversion centre and a distorted ZnO(6) octa-hedral coordination geometry arises from the two doubly deprotonated O,O',O''-tridentate ligands. In the crystal, the components are linked by N-H⋯O(a), N-H⋯O(...

Abstract In this study, Mn doped CdS/ZnO nanocomposites synthesized by co-precipitation method and its photocatalytic activity was tested using methylene blue under solar light irradiation. The prepared hybrid are characterized different physicochemical techniques including XRD, FESEM, EDX, TEM, UV-vis DRS PL analysis. From the XRD analysis, ZnO/CdS nanocomposite diffraction peaks only reflect ...
