In this paper, a diamine ligand of 2-(4-fluorophenyl)-5-(pyridin-2-yl)-1,3,4-oxadiazole (FPYOZ), which owned both enlarged conjugation chain with electron-pulling group and fluorine atom, was synthesized. Its corresponding Re(I) complex was also synthesized and studied in detail, including single crystal analysis, electronic structure, photophysical performance, thermal stability and electrochemical...
Erbium doped ZrO 2 (ZrO 2 :Er 3+ ) nanocrystals are prepared by a butadinol low thermal crystallization method. The crystallization temperature is reduced to 500°C. X-ray diffraction (XRD) spectra show there exists monoclinic and cubic ZrO 2 phases. Green, yellow and red lights are seen from the upconverting luminescence spectra under 980nm excitation. The results confirm...
