What is Photoluminescence and energy transfer of Tm3+ doped LiIn (WO4)2 blue phosphors about?
Room temperature steady and time resolved emission spectra of LiIn 1 À x Tm x (WO4)2 (where thulium concentration is 0, 0.5, 1, 5 and 10 at%) blue phosphors, under UV excitation energy have been investigated. The concentration quenching effect on the blue emission, due to the (WO 4 ) À 2 groups and 1 G 4 -3 H 6 emission transition of Tm 3 + were studied. Two energy transfer mechanisms are shown. The first takes place between excited (WO 4 ) À 2 groups and the 1 G 4 energy level of Tm 3 + , and is mainly analyzed by phonon-assisted energy transfer. The second mechanism is due to an energy transfer from the excited Tm 3 + ions to the surrounding ground state Tm 3 + ions. The non-exponential decay curves of the 1 G 4 level observed for higher concentrations are analyzed by the Inokuti-Hirayama model. We think that the quenching effect between Tm 3 + ions is mainly linked to the dipole-dipole interactions.
