Effect of surfactants on morphology and luminescent properties of Ca _3(VO_4)_2:Bi, Eu~(3+) red phosphors

摘要

Using anionic surfactant sodium dodecylbenzene sulfonate (SDBS), cationic surfactant cetyltrimethylammonium bromide (CTAB) and nonionic surfactant glyceryl monostearate (monostearin) respectively, Ca_3(VO _4)_2:Bi, Eu~(3+) 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 surfactants not only greatly influenced their morphology, but also induced a remarkable change value of I_(615)/I_(592). The reason that causes the variation of these properties for Ca_3(VO _4)_2:Bi, Eu~(3+) red phosphors was concluded to be related to different surfactants.
