Investigation Of Host-Sensitized Luminescence Of Trivalent Lanthanide Doped Yttrium Phosphate Using Vuv Spectroscopy, Zachary Way

All Master's Theses

Host-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 YPO₄:Ln³⁺ (Ln³⁺ = Sm³⁺, Eu³⁺ and Tb³⁺) were evaluated for two synthetic approaches. Electron-hole pair trapping efficiencies and S_loss values were calculated using published kinetic models.
