It is shown that the absorption spectra of PVK dopping rare earth complexes can be red shifted to the visible region and overlap with the emission spectrum of PVK, which makes the energy transfer possible from PVK to the rare earth ion.展开更多

X-ray diffraction analysis. adsorption technique, and cyclic voltammetry were used to characterize the material. The results show that [Fe(bpy)(3)](2+) has been entrapped in the supercage of zeolite, its electron transfer is realized by electron hopping of [Fe(bpy)(3)](2+) within the supercage of zeolite.展开更多
