Microstructure and photoluminescence properties of Sr2.91V2O8:Eu0.06 phosphors prepared by the solution combustion method |
| 초록 |
Eu3+- doped Sr3V2O8 phosphors have attracted interests due to their potential application in lamps, display source, and white LEDs. In this work, we studied the microstructure and photoluminescence (PL) characteristics of the Sr2.91V2O8:Eu0.06 phosphors synthesized by the solution combustion method. X-ray diffraction results showed that the fabricated phosphors had a single phase with the palmierite-type structure. The fabricated Sr2.91V2O8:Eu0.06 phosphors had nanocrystalline and high-quality powder characteristics, showing spherical and smooth morphology. The PL emission spectra exhibited the green broad emission band centered at 510 nm and the red sharp emission peak at 614 nm, which were caused by the charge transfer transitions of the VO43- group and the f-f level transition of Eu3+ ion, respectively. |
