KTb(MoO4)2 Green Phosphor with K+-Ion Conductivity: Derived from Different Synthesis Routes

Abstract: The influence of different synthesis routes on the structure and luminescent properties of KTb(MoO 4 ) 2 (KTMO) was studied. KTMO samples were prepared by solid-state, hydrothermal, and Czochralski techniques. These methods lead to the following different crystal structures: a triclinic scheelite-type α-phase is the result for the solid-state method, and an orthorhombic KY(MoO 4 ) 2 -type γ-phase is the result for the hydrothermal and Czochralski techniques. The triclinic α-KTMO phase transforms into the ortho… Show more

“…Luminescence properties are strongly dependent on various factors such as synthesis techniques, annealing temperature, grain diameter, size of coherent scattering regions (crystal size), and others. 34,35 In this work, we prepared K 5 Eu(MoO 4 ) 4 by various methods and tried to reveal the influence of synthesis techniques on material structure and luminescence properties.…”

“…Thus, the positions of the energy states for Tb 3+ and Eu 3+ contribute to the efficient transfer of energy from Tb 3+ to Eu 3+ . Earlier, the efficient energy transfer from Tb 3+ to Eu 3+ based on a dipole–dipole mechanism was found in other Mo-based phosphors. …”

“…Eu 3+ -containing Mo-based materials with different crystal structures were investigated for their potential as red phosphors due to the efficient 5 D 0 – 7 F 2 transition of Eu 3+ ions. , On the other side, the Tb 3+ ions are known as an excellent green-emitting activator due to the 5 D 4 → 7 F 5 transition. The usage of multiple activator ions, such as Eu 3+ and Tb 3+ , with the utilization of an energy transfer mechanism is an effective well-known strategy (the so-called co-doping strategy) for achieving a tunable multicolor emission inside a single phosphor host material. The Eu 3+ and Tb 3+ co-doping pair is regarded as an “effective pair” in the energy transfer process from Tb 3+ to Eu 3+ found in Mo-based phosphors. …”

“…Research efforts are ongoing to develop the fast K-ion conducting SSE materials, mainly including oxides, phosphidosilicates, antiperovskites, polymers, and composites. Currently, only a few K-ion SSEs have displayed ionic conductivities in a reasonable range for application in all-solid-state batteries (above 10 –4 S cm –1 ) at room temperature. For example, the T5 supertetrahedral phosphidosilicate KSi 2 P 3 displays a high bulk ionic conductivity of 2.6 × 10 –4 S cm –1 at 25 °C .…”
