Abstract
Using cationic surfactant cetyltrimethylammonium bromide (CTAB) and anionic surfactant sodium dodecylbenzene sulfonate (SDBS), respectively, YVO4: Bi, Eu3+ red phosphors were prepared by a facile reaction chemistry method and their morphology, structure and luminescent properties were investigated by scanning electron microscope (SEM), X-ray diffraction (XRD) and fluorescence spectrometer. The results showed that the introduction of cationic and anionic surfactants not only greatly influenced their morphology, but induced a remarkable change XRD patterns. The reason that causes the variation of these properties for YVO4: Bi, Eu3+ red phosphors was concluded to be related to different surfactants.
