在室温、pH为10的含银氨络合物和磷酸钠的稳定水溶液中，通过电化学产酸，在氧化铟锡(ITO)镀膜玻璃上电沉积Ag3PO4薄膜。释放的H+离子降低了ITO工作电极的局部pH，使Ag3 PO4离子从银氨络合物中解离出来，然后与PO4 3−反应生成Ag3 PO4。电沉积Ag3PO4薄膜的形貌与外加电压有关：在1.2V和1.6V时分别得到三八面体结构和四面体结构，而在1.6V和1.6V时得到四面体结构。测量了电沉积Ag3PO4薄膜的吸收光谱，其直接带隙和间接带隙分别为2.43 eV和1.99 eV。在pH值为7的可见光照射下，电沉积的Ag3PO4薄膜产生稳定的灵敏光电流。
Ag 3 PO 4 films were electrodeposited onto indium-tin oxide (ITO) coated glass through electrochemical generation of acid in a stable aqueous solution contained silver ammonia complexes and sodium phosphate at room temperature and pH 10. After the released H+ ions lower the local pH at ITO working electrode, Ag+ ions were dissociated from silver ammonia complex and then reacted with PO 4 3− to form Ag 3 PO 4 deposits on ITO. The morphologies of electrodeposited Ag 3 PO 4 films depended on the applied potentials: trisoctahedral like structure obtained at 1.2 V versus Ag/AgCl and tetrahedral structure obtained at 1.6 V versus Ag/AgCl. The absorption spectra of the electrodeposited Ag 3 PO 4 films were measured and they had direct and indirect band gaps of 2.43 eV and 1.99 eV, respectively. The electrodeposited Ag 3 PO 4 films produced stable sensitive photocurrent in response to visible light irradiation at pH 7.
