Effect of Excitation Wavelength on the Blue Emitting Sr2MgSi2O7 Phosphor

Abstract:

Long afterglow blue emission silicate (SMS) phosphor doped with Eu2+ and Ce3+ was synthesized via traditional solid-state reaction in the weak reducing atmosphere. X-ray diffractometer (XRD), field-emission scanning electron microscope (FE-SEM) and energy dispersive X-ray (EDX) spectroscope were employed to characterize its crystal phases, surface morphology and elements composition. The photoluminescence (PL) properties were characterized by PL Spectrophotometer. It was found that the excitation wavelength played a significant role in photoluminescence emission intensity.
