    摘要:

    采用溶胶-凝胶法,以六水硝酸锌和乙二醇单甲醚为主要原料,在SiO2玻璃衬底上旋涂一层致密的ZnO籽晶,用水热法,通过对ZnO籽晶层面朝下和朝上分别制备了ZnO纳米棒和微米棒。研究了不同生长液浓度对ZnO纳米/微米棒的形貌和光学性能的影响。结果表明,ZnO纳米棒直径约在(60~90) nm之间,长度约为1 600 nm,微米棒直径约(1~4) μm,长度约8~14 μm;随着生长液浓度的增加,ZnO纳米棒越致密,而ZnO微米梭生长成ZnO微米棒;ZnO纳米/微米棒的光致发光(PL)光谱强度随着生长液浓度的增加逐渐增强。

    Abstract:

    The ZnO seed layer had been prepared by the method of SolGel dip coating method on SiO2 substrate. The seed layer was relatively dense. And the zinc nitrate hexahydrate [Zn(NO3)2·6H2O] and the glycol monomethyl ether(C3H8O2) were the main raw materials.The ZnO nan/micro rods were prepared with the seed layer placed face down and up.The effects of different growth liquid concentration on the morphology and the optical properties of ZnO nano/micro rods were investigated.The results showed that the diameter of the prepared ZnO nano rod was about (60~90) nm,the length was about 1 600 nm,and the diameter of the ZnO micro rod was about (1~4) μm,the length was about 8 to 14 μm.The ZnO nano rods were more dense with the increase of the 〖JP2〗growth liquid concentration and the ZnO micron shuttle was grown to be the ZnO micron rod.The photoluminescence(PL)〖JP〗 spectra intensity of ZnO nano/micro rods were enhanced with the increase of the growth liquid concentration.
