The results show that the particles in the two phosphor samples are overall spherical-shaped with a mean size of ~300 nm, and their main emission peaks under 147 nm VUV excitation are located at 619 nm. In comparison with Y0.95Eu0.05PO4 phosphor, Y095Eu0.05 (P0.2V0.8)O4 phosphor is a more promising candidate for red-emitting PDP phosphor application due to its higher homochromy and its chromaticity coordinates closer to flammulated chromaticity coordinates (0.67, 0.33) regulated by National Television Standard Committee.
