以Zn（NO3）2和Al（NO3）3为原料，乙二胺为溶剂，在348 K下加热24 h，制备了Zn-Al层状双氢氧化物（LDH）。所得颗粒具有片状形态，在水中分散良好。在无碱玻璃衬底上干燥LDH纳米粒子溶胶，容易获得LDH薄膜。在高于573 K的温度下焙烧LDH膜产生高度取向的氧化锌膜。所得薄膜在玻璃衬底上具有氧化锌（002）取向。这种取向反映了LDH膜的取向。当波长为400 nm时，氧化锌薄膜的透光率达到80%以上。
The Zn–Al layered double hydroxide (LDH) particles were prepared by heating aqueous solutions of Zn(NO3)2and Al(NO3)3with ethylenediamine at 348K for 24h. The obtained particles, which had sheet morphology, were well dispersed in water. The sol of LDH nanoparticles was dried on an alkali-free glass substrate and LDH thin films were obtained easily. Firing the LDH films at temperatures higher than 573K produces a highly oriented zinc oxide film. The obtained films had orientation of zinc oxide (002) on the glass substrate. This orientation reflected that of the LDH films. The zinc oxide films showed more than 80% of the optical transmittance when the wavelength was 400nm.
