In this paper,a simple and effective method to prepare amorphous ZnO nano-powder by low temperature pyrolytic reaction is reported.

In this paper,amorphous ZnO thin film was prepared by sol-gel method on glass substrate in order to study optical properties.

Studies on defect structures of Mn~(2+) and Fe~(3+) impurity centers in ZnO crystals;

Different Zn salts including Zn(CH_3COO)_2·2H_2O,ZnCl_2,Zn(NO_3)_2·6H_2O and ZnSO_4·7H_2O and different alkalies including NaOH and KOH were used as raw materials to produce the precursory solution Zn(OH)~(2-)_4,and ZnO crystals were synthesized when Zn(OH)~(2-)_4 decomposed in hydrothermal environment.

ZnO crystal has many good physical and chemical properties,which make it possible to be a promising material for the next generation optoelectronic application.

Tetrapod-shaped zinc oxide(T-ZnO) whiskers were prepared by the method of vapor phase oxidation at high temperature with bentonite as catalyst,and the influence of experimental conditions to T-ZnO whiskers were discussed in this article.

Nickel coatings were prepared on the surface of T-ZnO whiskers by electroless plating technique.

The growth mechanisms are investigated for the two ZnO whiskers with differentmorphology.

Influence of ZnO seed grains on microstructure and varistor characteristics in ZnO-Bi_2O_3-TiO_2-Sb_2O_3 ceramic system;
