查询词典 synthesizing

The characters of powder are connected with the inside structure and synthesize-technics of materials. In this paper, we want to search a optimize technics of materials synthesizing, and prepare a kind of nanosize powder which shape like ball and have good dispersed character. At the same time, we want to obtain a bridge structure of Zn-O-Tb through dopping of Tb, which can achieve efficient energy transfer from ZnO hosts to excited states of dopants, The doped powder can eradiate blazing green light because of efficient emission buildup from dopants and ZnO hosts, and the powder can emission a pure light. And we want to research the structure in doped ZnO for the further research of low-tension fluorescence of ZnO.
