Synthesis and Characterization of the Layered Hybrids (CnH2n+1NH3)2MCl4 (M=Co,Cu,Zn and n=2,4,6,8,10,12)
A series of hybrids (CnH2n+1NH3)2MCl4 with quantum-well energy-band structure were synthesized by chemical reaction in HCl solutions, in which M(Co,Ni,Cu,Zn) and n(2,4,6,8,10,12) varied to adjust the quantum-well depth and the barrier width, respectively. The X-ray diffraction patterns and scanning electron microscopy images of the products demonstrate that they crystallize well with the typical layered structures. However, the analogues of Ni can not be successfully synthesized in the same way. Concerning the energy-band structure, the colors of the products reveal that the quantum-well depth is more important than the barrier width for controlling the properties of the hybrids.
