用CTAB辅助水热法合成了四方相的SrWO4∶Eu3+纳米晶体。通过X射线衍射仪和扫描电子显微镜等测试手段对样品进行了表征。SrWO4∶Eu3+纳米晶粒尺寸随着反应溶液中Eu3+离子和CTAB含量的增加而减小。在393 nm光激发下,观察到5D0→7F J(J=1,2,3,4)和5D1→7F0跃迁,并且5D0→7F2跃迁的发射最强,表明Eu3+在SrWO4基质中占据了非对称中心的格位。发射峰的位置与激发波长无关。 Tetragonal SrWO4: Eu3 + nanocrystals were synthesized by CTAB assisted hydrothermal method. The samples were characterized by X-ray diffraction and scanning electron microscopy. The size of SrWO4:Eu3 + nanocrystals decreases with the increase of Eu3 + ion and CTAB content in the reaction solution. The 5D0 → 7F ​​J (J = 1, 2, 3, 4) and 5D1 → 7F0 transitions were observed at 393 nm and the strongest emission was observed for the 5D0 → 7F2 transition, indicating that Eu3 + occupies an asymmetric position in the SrWO4 matrix Center of the grid. The location of the emission peak has nothing to do with the excitation wavelength.
