Crystals of Zn(NO3)2 · H2O and Mn(NO3)2 · 2 H2O were synthesized by heating melts of the respective penta- or hexahydrates. Single crystal X-ray diffract... Manfred Wildner,Gerald Giester,Christian L. Lengauer,... - 《Zeitschrift für Kristallographie - Crystalline Materials》 被引量...
Moreover, three-dimensional Zn-3(VO4)(2) microspheres could be formed through calcination of the Zn3V2O7(OH)(2)center dot 2H(2)O precursor. The obtained Zn3V2O7(OH)(2)center dot 2H(2)O and Zn-3(VO4)(2) microspheres were further investigated as the anode materials of lithium-...
An interesting structure containing an “open-box” molecule [Co4(Hpdc)4(py)12]⋅4 py⋅2 H2O⋅2 CH3OH (6) (py=pyridine) has been isolated by using dehydrated [Co(H2pdc)2] as the precursor, and its crystal structure has been analyzed. Crystal data for...
In this study, the light harvest ability is improved as (Bi 1 xZn x)S QD complex and multilayer structure are fabricated by using two QD materials (Bi 2S 3, ZnS). The band gap energy is controlled by the amount of the bismuth(Bi) and the zinc(Zn). And then, the light absorbance ...
