Ethylenediaminium niobium oxyfluoride.

The title compound, bis(ethylenediaminium) mu-oxo-bis[tetrafluorooxoniobium(V)], (C2H10N2)2[Nb2O3F8], is a novel organically templated niobium oxyfluoride. It consists of isolated [Nb2O3F8]4- octahedral dimers charge balanced by ethylenediaminium cations, two of which lie about inversion centres. Two NbO2F4 octahedra are fused through a common O atom to form the dimers. Characteristic short ter...

Upconversion luminescence in Er-doped germanate-oxyfluoride and tellurium-germanate-oxyfluoride transparent glass-ceramics

Upconversion luminescence has been studied for Er in a germanate-oxyfluoride and a tellurium-germanate-oxyfluoride transparent glass-ceramic using 800 nm excitation. Significantly increased upconversion luminescence was observed from transparent glass-ceramics compared with that from their corresponding as-prepared glasses. In addition to a strong green emission centered at 545 nm from S3/2 sta...

Probing the Local Chemical and Structural Ordering of Iron Oxyfluoride

Scanning transmission electron microscopy (STEM)-electron energy loss spectroscopy (EELS) has been used for studying local structure of the energy related materials. High resolution (Cs-corrected) STEM is regarded as a promising technique to observe morphological evolution and atomic arrangement inside single particles. Combining with EELS technique, one could probe the local chemical structure...
