Abstract：

In　this　work,　4　at%　Dy3+:　YAG　(Dy:　YAG),　4　at%　Dy3+/0.5　at%　Tb:　YAG　(Dy/Tb:　YAG),　4　at%　Dy3+/0.5　at%　Eu3+:　YAG　(Dy/Eu:　YAG),　0.5　at%　Tb:　YAG　(Tb:　YAG),　and　0.5　at%　Eu3+:　YAG　(Eu:　YAG)　crystals　have　been　syn-thesized　by　the　Czochralski　method.　Optical　absorption　and　luminescence　spectra　of　Dy:　YAG,　Dy/Tb:　YAG,　and　Dy/Eu:　YAG　crystals　are　contrasted　and　discussed.　Through　emission　decay　times　of　Dy3+:　F-4(9/2)　level　in　related　crystals　and　the　fluorescence　spectra　under　different　excitations,　the　energy　transfer　pathways　between　Dy3+　and　Tb3+,　and　Dy3+　and　Eu3+　ions　are　explored.　Additionally,　Judd-Ofelt　analysis　is　performed　to　estimate　distinct　spectroscopic　factors　like　radiative　transition　rates,　fluorescence　branching　ratios,　and　radiative　lifetimes.
