以ITO导电玻璃为基材,采用溶液化学法分两步制备CePO4及Eu3+掺杂CePO4一维纳米薄膜.研究底膜液提拉次数、底膜厚度、陈化液pH值和陈化时间等对薄膜形貌的影响.采用扫描电子显微镜、X射线衍射仪和荧光分光光度计等对CePO4及Eu3+掺杂CePO4一维纳米薄膜进行表征.结果表明,用无水乙醇底膜液,提拉3~6次,经350℃煅烧,在pH值为1.4~1.6的水相陈化液中,90℃水浴陈化3~6 h,即可在ITO导电玻璃上制得平整致密,具有较大比表面积的六方晶相CePO4及Eu3+掺杂CePO4一维纳米薄膜.
Using ITO conductive glass as substrate, CePO4 and Eu3 + -doped CePO4 nanofilms were prepared in two steps by solution chemistry method.The effects of extraction times, thickness of the base film, pH of the solution and aging time The morphology of CePO4-doped CePO4 nanofilms was characterized by scanning electron microscopy, X-ray diffraction and fluorescence spectrophotometer.The results showed that the CePO4 nanofilms doped with CeOH and Eu3 + 6 times, calcined at 350 ℃, aged at 90 ℃ for 3 ~ 6 h in a water-phase aged solution with a pH value of 1.4-1.6, which can be made into a dense and dense surface with a large specific surface area Of hexagonal CePO4 and Eu3 + doped CePO4 one-dimensional nano-film.
