Abstract: | MWO4:Sm3+ (M = Ca, Sr and Ba) red phosphors with spherical microparticles were successfully prepared via a mild and facile hydrothermal route. The crystal structure and particle morphology were investigated by the X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively. Photoluminescence excitation and emission spectra and decay curve were used to characterize the luminescence properties of the MWO4:Sm3+ phosphors. The excitation spectra indicate that MWO4:Sm3+ phosphors can be excited effectively by the UV InGaN light-emitting diode (LED), and the emission spectra show that the phosphors can emit strong red light from 600 to 650 nm. Therefore, it is considered to be a new promising red phosphor for white LED application. |
