Enhanced Luminescent of Y(P,V)O4:Eu3+ Nano Phosphors in Porous Cellulose Fibers by Facile Liquid Phase Precursor Synthesis

This paper reports an approach for enhancing the luminescent properties Of Y-0.97(P-0.845 V-0.455)O-4:Eu-0.03(3+) nano phosphors with cellulose using a liquid phase precursor (LPP) process. The resulting Y-0.97(P0.845V0.455)O-4:Eu-0.03(3+) nano phosphors were characterized by transmission electron microscopy, VUV photoluminescence spectroscopy and particle distribution analysis. The nano phosphors obtained had a uniform particle size of approximately 13-14 nm. The TG/DTA reveals that during heating, the weight loss occurs in two steps during heating. The DTA peak intensities of these exothermic peaks suggest burning and decomposition of the cellulose pulp. The amount of residue of the composites increases with increasing Y(P,V)O-4:Eu3+ solution content. These results indicate that the introduction of nanocrystalline Y(P,V)O-4:Eu3+ in cellulose does not reduce the thermal stability, and suggest some miscibility between the cellulose and inorganic particles. The VUV photoluminescence results showed the maximum peak intensities of the phosphor, Y-0.97(P0.845V0.455)O-4:Eu-0.03(3+), to be 70.12% of that for the commercial bulk sample. These results suggest that Y-0.97(P0.845V0.455)O-4:Eu-0.03(3+) is a promising alternative red-emitting plasma panel display (PDP) phosphor to the commercial Y(P,V)O-4:Eu3+ samples.
