| 摘 要： | 在前驱体溶液中添加和不添加碳纳米管，采用简单的水热合成法并在1000℃下烧结，获得树枝状和类球状纳米结构的 YBO3：Eu3＋样品．研究表明：对于树枝状结构的样品，其红色和橙色光的强度比更高，且其CIE 坐标为（0．67，0．33），几乎与商业红色荧光粉 Y2 O2 S ：Eu3＋的色坐标相同，可见树枝状结构的红色荧光粉YBO3：Eu3＋在纳米器件和照明器件中具有潜在应用价值．该文还对样品的发光性质和机制做了解释．

| Abstract: | The dendritic and spherical‐like YBO3 :Eu 3 + nanostructures were synthesized by a facile hydrothermal method and subsequently annealed at 1 000 ℃ with and without additive carbon nanotube in the precursor solution .Compared with spherical‐like sample ,the sample with dendritic structure had higher red to orange ratio ,and its CIE coordinate (0 .67 ,0 .33) matched better with that of commercial red phosphors Y2 O2 S :Eu 3 + ,indicating good color purity ,which could be used as potential candidates for nano‐devices and lighting devices . The luminescence properties and mechanism were also explained . |
