“…Coreshell type hybrid structure, as a typical structure of quantum dots system, has important theoretical research value and exhibits novel properties [6][7][8][9]. Thus it is promising to use the core-shell structure to change some properties, such as surface modification through shell building.…”

a b s t r a c tIn this work, ZnO-CuO core-shell hybrid nanospheres with well-crystalline wurzite ZnO core and monoclinic CuO shell were successfully synthesized through a two-stage solution process. The as-prepared nanocomposites were carefully characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), and UV/Vis diffuse reflection spectroscopy (DRS). Compared with bare ZnO cores, the ZnO-CuO core-shell 0-dimensional nanocomposites had greatly enhanced absorption strength and dramatically broadened optical response ranging from near-ultraviolet to visible light, which was probably attributed to heterojunction between n-ZnO core and p-CuO shell and defects originated from synthetic procedure. The as-synthesized p-CuO/ n-ZnO core-shell hybrid structure may lead to tantalizing applications including solar energy materials, LED and optical sensor.

“…16,[20][21][22] Currently, three precursor systems are usually adopted for the LPD method: (1) SnF 2 aqueous solution, 23 (2) a mixed solution of SnF 2 , H 2 O 2 and HF/H 3 BO 3 , 5,24 or (3) (NH 4 ) 2 SnF 6 aqueous solution. 25 These three systems are still unsatisfactory, because they are uncontrollable, releasing corrosive and toxic HF etc. Here, a new precursor system containing CaO 2 $8H 2 O and SnF 2 aqueous solution has been developed for the SnO 2 inverse opal structure by the LPD method.…”
