Investigation of Host-Sensitized Luminescence of Trivalent Lanthanide Doped Yttrium Phosphate using VUV Spectroscopy
Abstract
dc:description.abstractHost-sensitized luminescence of yttrium phosphate doped with trivalent lanthanide elements prepared via two synthetic approaches was studied using VUV spectroscopy. A correlation between an unusually intense 150 nm excitation intensity and the ground state energy level of select trivalent lanthanide elements was proposed. Using spectroscopy, the host-to-activator transfer efficiencies of YPO<sub>4</sub>:Ln<sup>3+ </sup>(Ln<sup>3+</sup> = Sm<sup>3+</sup>, Eu<sup>3+</sup> and Tb<sup>3+</sup>) were evaluated for two synthetic approaches. Electron-hole pair trapping efficiencies and S<sub>loss</sub> values were calculated using published kinetic models.
