采用电池电化学技术制备了高结晶度的AMO_4（A=Ca，Sr，Ba; M=W，Mo）发光薄膜。研究表明，沉积速率可以通过调节温度和pH值来调节。其最适温度为308 ~ 333 K，最适pH值为12 ~ 13.5。X射线衍射和光电子能谱分析表明，薄膜为多晶AMO 4（A=Ca，Sr，Ba; M=W，Mo）。在电池条件下，由于大的晶体团簇的消失，薄膜的均匀性得到了显著改善。在室温下，当激发波长为201 nm时，可观察到从紫色到可见光的宽发射带。进一步的分析表明，这样一个宽带可以分为两个子带。它们的中心分别位于357和456 nm。据推测，较长波长的发射可能来自MoO 42 −络合物。
Highly crystallized luminescent AMO4(A=Ca, Sr, and Ba; M=W, Mo) thin films have been prepared by cell electrochemical technique. Researches reveal that the deposition rate can be tailored by adjusting temperatures and pH values. The optimum temperature is between 308 and 333K, and the pH value is between 12 and 13.5. X-ray diffraction and photoelectron spectra examinations confirm that the obtained films are polycrystalline AMO4(A=Ca, Sr, and Ba; M=W, Mo). Under cell conditions, the homogeneity of films has been improved markedly due to the disappearance of large crystal clusters. At room temperature, a broad emission band ranging from the violet to visible can be observed with the excitation wavelength at 201nm. Further analyses show that such a broad band can be divided into two sub-bands. Their centers are situated at 357 and 456nm, respectively. It is proposed that the longer wavelength emission probably originates from MoO42−complex.
