在水溶液中，采用阳极电化学产酸法在氧化铟锡（ITO）电极上生长CeF 3薄膜。在薄膜电沉积过程中，水的电化学氧化降低了ITO阳极电极表面的局部pH值，降低了Ce-乙二胺四乙酸二钠络合物的稳定性，释放出游离的Ce离子与F-反应，在ITO电极上形成CeF 3沉积物.该方法也被推广到CeF 3：Tb薄膜的生长.研究了电沉积CeF 3和CeF 3：Tb薄膜的光学性质，两种薄膜在紫外光激发下均表现出强烈的光致发光。
CeF 3 films have been grown on indium tin oxide (ITO) electrode through anode electrochemical generated acid in aqueous solutions. For the film electrodeposition, the local pH at the ITO anode electrode surface is decreased by electrochemically oxidizing water, and the stability of the Ce―ethylene diamine tetraacetic acid disodium complex is decreased to release free cerium ions to react with F- to form CeF 3 deposits onto the ITO electrode. The procedure was also extended to grow CeF 3 :Tb films. The optical properties of electrodeposited CeF 3 and CeF 3 :Tb films have been explored, and both films exhibit intense photoluminescence under UV excitation.
