Preparation of YVO4:Eu3+ Red Phosphor by Combustion Synthesis and its Luminescence Properties
YVO4:Eu3+ red phosphor was prepared by combustion synthesis without any post heat treatment at 700 oC-900 oC, using urea, oxalate acid and metal nitrates as raw materials. The product can emit bright red light under ultraviolet light irradiation. The phase compositions and luminescence properties were studied via X-ray diffraction (XRD) and photoluminescence spectra. The experimental results indicated that addition of appropriate amount of fuel and oxalate acid is favorable for the improvement of luminescence intensity.
