This thesis hydrothermal Be sheet metal as a reactive substrate were successfully prepared by different morphologies nano (micro) crystalline inorganic thin film composed of: aluminum hydroxide and ZnSe polycrystalline thin films. Aluminum hydroxide is excellent flame retardant and an inorganic filler material prepared alumina, nano-alumina is widely used in structural ceramics, catalyst carrier, fine ceramics, porous filter, integrated circuit substrate material, fast ion conductor composite material, fluorescent materials, moisture-sensitive sensors and infrared absorption material and other new materials. ZnSe having a good transmission properties, is an ideal material for manufacturing of optoelectronic devices. ZnSe semiconductor material with a blue laser and light emitting diodes in underwater communications, telecommunications, photocopying, high-density information storage, high-resolution image display signal indication and medicine, basic research, environmental testing, field testing and other aspects of biochemistry has a very broad application prospects. 1 with the Al film as a substrate and a reactant, flaky aluminum hydroxide prepared nm (micron) thin films, which are discussed cetyl trimethyl ammonium bromide (CTAB) is added in an amount, hexamethylenetetramine amine (HMT) amount of added aluminum hydroxide solvent composition ratio of microcrystalline morphology. Powder X-ray diffraction sample (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were characterized. Powder X-ray diffraction (XRD) results show that the sample obtained aluminum hydroxide, is mainly β-AlOOH. Experimental results show that: CTAB and HMT is added, reaction temperature, reaction time, type of solvent, the composition ratio of aluminum hydroxide sample morphology to a certain extent. CTAB is added when the reaction system, the hydrogen was thin aluminum sheet sample; when CTAB was not added to the reaction system, the sample showed a thicker sheet; HMT added with increase in the amount of aluminum hydroxide microchip gradually becomes dense, forming the sheet into a flower-like microcrystalline structure assembled; DMF as a solvent to increase the proportion of aluminum hydroxide grow slightly sparse microchip. 2 Zn film as the substrate using the reactant, selenium powder as Se source, sodium sulfite as reducing agent, by hydrothermal method, preparation of the ZnSe thin film composed of particles. Control mixed solvent composition, reaction temperature, the CTAB surfactant is added in an amount of microcrystalline prepared ZnSe thin film composed of a spherical and irregular film composed of nanoparticles. Discuss the mixed solvent, reaction temperature, surfactant CTAB addition on the morphology of the sample. The experimental results showed that: when the solvent is ethylene glycol and water (1:1, v / v), the crystallite constituting the film is a hollow rod shape; when the solvent is water, the spherical microcrystalline constituting the film. With the increase of the amount CTAB, the irregular morphology of nanoparticles sample shape, assembled into spherical nanoparticles. When the reaction temperature from 150 ℃ up to 170 ℃, the zinc becomes easy microcrystalline ZnSe chip off, that the reaction is particularly severe at high temperatures, is not conducive to the formation of ZnSe films. Paper discusses the different formation mechanism of ZnSe crystallite morphology. Samples obtained powder X-ray diffraction (XRD) and scanning electron microscopy (SEM) were characterized.
