分别通过溶胶凝胶、水热法合成了上转换发光材料 Er3＋∶Y3 Al5 O12和 Er3＋∶Y3 Al5 O12／ZnS 复合物，并采用 XRD 和 SEM 进行表征，研究了 Er3＋∶Y3 Al5 O12／ZnS 在可见光照射下降解次甲基蓝的催化活性。讨论了 Er3＋∶Y3 Al5 O12掺杂量、可见光照射时间、光照强度、催化剂的量、处理温度和处理时间对降解率的影响，并且与单一ZnS 可见光光催化性能进行了比较。结果表明，加入上转换发光材料 Er3＋∶Y3 Al5 O12后降解率大幅度增加，且它掺杂量为10％时对染料废水的降解效果最好。

An upconversion luminescence agent Er3+ ∶Y3 Al5 O12 mixed with the ZnS composites was synthe-sized by using sol-gel method and the hydrothermal method.The Er3+ ∶ Y3 Al5 O12/ZnS composites were characterized by XRD and SEM .Its photocatalytic activity was investigated as well through the photocata-lytic degradation of the methylene blue under the visible light irradiation.The influence of the doping a-mount of Er3+ ∶Y3 Al5 O12 ,the visible light irradiation time,the illumination intensity,the dose of catalyst, the heat-treated temperature and heat-treated time on the degradation rate were investigated,and compared with the visible light catalytic of common ZnS.The results revealed that the degradation rate increased sig-nificantly by adding upconversion luminescence agent Er3+ ∶Y3 Al5 O12 .The photocatalytic decomposition of the dyestuff waste water achieved the optimal effect when the 10% of the amount of upconversion lumi-nescence agent.
