将原料封装入真空石英管,在873 K进行固相反应制备了Li掺杂的Cu_(1-x)Li_xInSe_2(x=0–0.4)块体材料,并对该材料的结构、电学和光学特性进行了系统性的研究。Li掺杂之后,样品的晶体结构还保持黄铜矿结构,并能得到更大的晶粒。而电阻率从1.98×10~2??cm增大到2.73×10~8??cm。光学能隙也从0.90 e V提高到1.33 e V,增大了光伏开路电压。实验结果表明,Li掺杂的Cu_(1-x)Li_xInSe_2能有效提高光电材料的性能。

A tri(8 quinolinol)nickel coordination compound, [Ni 2(HQ) 3Q 3] ClO 4, was synthesized and its crystal structure was determined by X ray diffraction. The crystal structure indicated a space group of P2 1/c with a =1.613 8(1) nm, b =1.590 0(1) nm, c =1.939 9(1) nm, β =94.663(2)°, V = 4.961 2(6) nm 3 and Z =4. Three strong hydrogen bonds were found in each unique unit between two tri(8 quinolinol) nickel fragments.
