We have demonstrated the first observable case of efficient energy transfer from poly-ligands to terbium ions through cross-linked siloxane in solution. The intensification of green luminescence was easily perceived by the naked eye under UV-254 nm illumination, where even the terbium dopants reached 0.1 μM. Moreover, the nano-scale fibrous structure (diameter 100-200 nm) aggregated to a micro-...

Bismuth vanadate (BiVO4) is a narrow-bandgap semiconductor (~2.41 Ev) that responds to visible light. The efficiency of degradation organic dyes indexed by methylene blue (MB). After 150 min, the MB pure BiVO4 was about 20%. Its adsorption performance and electron–hole pair migration ability are weak, photocatalytic activity needs be improved. doped with rare earth ions can facilitate separatio...

We report the structural, magnetic, and interfacial spin transport properties of epitaxial terbium iron garnet (TbIG) ultrathin films deposited by magnetron sputtering. High crystallinity was achieved growing on gadolinium gallium (GGG) substrates either at high temperature, or room temperature followed thermal annealing, above 750 {\deg}C in both cases. The display large perpendicular magnetic...
