摘要

Well-crystallized tetragonal YPO4 and YPO4:Ln(3+) (Ln = Eu, Tb) nanocrystals with cuboid morphology and narrow size distribution have been successfully synthesized through a facile two-step hydrothermal synthesis route using Y4O(OH)(9)NO3 as a sacrificial precursor for the first time. The structure, morphology and phase evolution process were significantly affected by the reaction conditions (hydrothermal treatment time and concentration of (NH4)(2)HPO4). The luminescence colors of YPO4:Tb3+, Eu3+ phosphors can be easily tuned from green to primrose yellow and then to white by adjusting the concentration of Eu3+ ions under 373 nm irradiation. Furthermore, the energy transfer efficiency of YPO4:0.08Tb(3+), xEu(3+) increased gradually and reached about 94.30% when the concentration of Eu3+ ions was 0.10. The energy transfer mechanism from Tb3+ to Eu3+ has been proved to be a quadrupole-quadrupole interaction mechanism. These merits manifest that the yttrium phosphate phosphors with tunable white light emission may have potential applications in white light-emitting diodes.
