Magnetism and optical properties of Yb3Al5O12 hosted Er3+ – experiment and theory

Using the recently developed method based on a combination of DFT plane wave code applied to extract the crystal field parameters and a local atomic like Hamiltonian involving electron-electron, spin-orbit and Zeeman terms we calculated the energy levels of ground and excited multiplets of Yb3+ and Er3+ ions hosted in ytterbium and yttrium aluminum garnet (YbAG and YAG) including their crystal and magnetic field splitting. The obtained energy levels and derived magnetic properties are compared with the experimental data from magnetometry, photoluminiscence and near-infrared spectroscopy.

NaYF4:Yb,Er/NaYF4 Core/Shell Nanocrystals with High Upconversion Luminescence Quantum Yield

Upconversion core/shell nanocrystals with different mean sizes ranging from 15 to 45 nm were prepared via a modified synthesis procedure based on anhydrous rare-earth acetates. All particles consist of a core of NaYF4:Yb,Er, doped with 18 % Yb3+ and 2 % Er3+, and an inert shell of NaYF4, with the shell thickness being equal to the radius of the core particle. Absolute measurements of the photoluminescence quantum yield at a series of different excitation power densities show that the quantum yield of 45 nm core/shell particles is already very close to the quantum yield of microcrystalline upconversion phosphor powder. Smaller core/shell particles prepared by the same method show only a moderate decrease in quantum yield. The quantum yield of 15 nm core/shell particles, for instance, is reduced by a factor of three compared to the bulk upconversion phosphor at high power densities (100 W cm?2) and by approximately a factor of 10 at low power densities (1 W cm?2).

Core-shell metal fluoride nanoparticles: Via fluorolytic sol-gel synthesis-a fast and efficient construction kit

An efficient, fast and easy construction kit using the fluorolytic sol-gel synthesis of rare-earth-doped alkaline earth fluoride core-shell nanoparticles at room temperature is presented, capable of synthesizing several hundred grams to kilograms of core-shell particles in one batch. We show ways for an effective design of energy transfer core-shell systems. Undoped metal fluoride shells rigorously shield a luminescent core from the surrounding solvent, resulting in higher quantum yields, longer lifetimes of the excited states, and finally a brighter luminescence. The heavy SrF2 shields a luminescent core from the surrounding solvent three times more effectively than the light CaF2. Energy transfer processes from core to shell are more efficient than vice versa, and hence, absorbing cores are more effective than absorbing shells. The application of these materials in the preparation of transparent tunable luminescent materials showing different luminescence colours upon different excitation wavelengths is demonstrated.
