首次采用水热法制备了Eu3+掺杂的CdWO4。对Eu3+掺杂的CdWO4的结构、形貌和发光性能进行了表征。透射电子显微镜结果表明，纯的CdWO4为纳米棒，宽度约为50 nm。Eu~(3+)掺杂的Cd-WO_4配合物的光致发光性质表明，能量从WO_42-−基团转移到Eu~(3+)，表明Eu~(3+)有效地掺杂到了Cd-WO_4晶格中。通过对甲基橙(MO)的光降解实验，考察了CdWO4和Eu3+掺杂的CdWO4的光催化活性。Eu~(3+)掺杂的CdWO_4光催化降解MO的活性有所提高。用对苯二甲酸光致发光法(TA-PL)对羟基自由基进行了检测，其变化规律表明羟基自由基可能是活性物种。
Eu3+-doped CdWO4 was prepared for the first time by a hydrothermal method. The structure, morphology, and luminescence of the Eu3+-doped CdWO4 were characterized. TEM results revealed that the pure CdWO4 was a nanorod with a width of about 50 nm. The photoluminescent properties of Eu3+-doped CdWO4 complexes indicated energy transfer from WO42− groups to Eu3+ and suggested effective doping of Eu3+ into the lattice of CdWO4. The photocatalytic activity of CdWO4 and Eu3+-doped CdWO4 was investigated by the photodegradation of methyl orange (MO). Eu3+-doped CdWO4 had enhanced photocatalytic activity in the photodegradation of MO. The hydroxyl radical was detected by the terephthalic acid photoluminescence (TA-PL) method, and the regular change revealed that the hydroxyl radical may be the active species.
