以水、乙醇、乙二醇和甘油为反应介质，煅烧，采用溶剂热法制备了线状和近球形的eu2o3掺杂氧化钇（3mol%） [Y2O3:Eu(3mol%)]。在水和乙醇中制备的粉末具有线状结构，其中在水中处理的粉末具有较高的长径比，而在乙醇中处理的粉末具有较低的长径比。在乙二醇和甘油中制备的粉末具有分散良好的近球形粉末，其光致发光强度与未经溶剂热处理的亚微米颗粒几乎相同。
Eu2O3-doped yttrium oxide (3mol%) [Y2O3:Eu(3mol%)] with wire-like and near-spherical morphologies were prepared by a solvothermal treatment using water, ethanol, ethylene glycol and glycerol as reaction media followed by calcination. The powders prepared in water and ethanol possessed wire structure, where the powder treated in water showed high aspect ratio and that in ethanol showed low aspect ratio. The powders prepared in ethylene glycol and glycerol possessed well-dispersed near-spherical powders, which showed almost the same level of photoluminescence emission intensity as that of submicron particles prepared without solvothermal treatment.
