| Popis: | Eu3+-doped Ba3YP3O12 nanoparticles were prepared by the solution-combustion method. Rietveld refinement confirmed that the system crystallizes in cubic structure with I-43d (2 2 0) space group. Spherical shaped particles in nano range were observed which are responsible for improved luminescence. The 4.9 eV optical band-gap of the host shows that it as a good aspirant for lanthanide activators. The Photoluminescence emission spectrum demonstrates prevailing emission peak assigning to 5D0→7F2 transition at 612 nm of Eu3+ ions when energized at a wavelength of 394 nm. CIE color coordinates (x, y) exposed red emission, making this nanophosphor a potential candidate in NUV excited WLEDs. |
