A new class of lanthanide luminescent MOFs was constructed by encapsulating Ln3+ into the pores of MIL-121 (Ln3+@MIL-121). Ag+ was found to be able to greatly enhance the weak visible or NIR luminescence of Ln3+@MIL-121 since it can induce more efficient intramolecular energy transfer from the ligand to Ln3+ in Ag–Ln co-doped MOFs.

Pyrene-appended ytterbium complexes have been prepared using Ugi reactions to vary the chromophore–lanthanide separation. Energy transfer from the chromophore triplet is relatively slow, and gives rise to oxygen-dependent luminescence.

Microanalysis by EELS has been developing rapidly and though the general form of the spectrum is now understood there is a need to put the technique on a more quantitative basis (1,2). Certain aspects important for microanalysis include: (i) accurate determination of the partial cross sections, σx(α,ΔE) for core excitation when scattering lies inside collection angle a and energy range ΔE above the edge, (ii) behavior of the background intensity due to excitation of less strongly bound electrons, necessary for extrapolation beneath the signal of interest, (iii) departures from the simple hydrogenic K-edge seen in L and M losses, effecting σx and complicating microanalysis. Such problems might be approached empirically but here we describe how computation can elucidate the spectrum shape.The inelastic cross section differential with respect to energy transfer E and momentum transfer q for electrons of energy E0 and velocity v can be written as
