Synthesis of new Tb-doped Zn-Al LDH/tryptophan hybrids and their fluorescent property陈玉凤1,王肖庆1,罗世地2,鲍垚11. College of Chemistry,Nanchang University2. Department of Applied Chemistry,Guangdong Ocean.... Fluorescent spectra suggested that the green emission due to 5D4→7F5 transition of Tb3+ greatly decreased but not quenched, and the emission attributed to Try obviously increased. Meanwhile the fluorescent......

Impedance Spectroscopy of Ion Beam Mixed Cu/BaTiO3PTCR Ceramics雷家珩摘 要:The positive temperature coefficient resistance ( PTCR) barium titanate ceramic samples have been prepared by the standard solid-state reaction method, and the ceramic samples have been treated by depositing copper films with magnetron sputtering method. The metallic copper films......
. Then, the fluorescent property of the composites was studied. It is found that the fluorescence intensity of the composites increase linearly with the contents of the rare earth complexes increasing. Key words:fluorescent property; Eu; Gd; citric acid; doped complex; silicon rubber; rare earths; [全文内容正在添加中] ......
RAMAN AND IR SPECTROSCOPY OF PTCR Ba1-xPbxTiO3 CERAMICS王国梅,雷家珩,恽怀顺,薛理辉,王勤摘 要:<正>Raman and IR spectra of Nb-dopedPTC Ba1-xPbxTiO3, semiconducting ceramics (x=0, 0.28, 0. 296, 0. 313, 0. 330, 0. 370 ) have been neasured,and mode assignments of Raman scattering frequenciesand itfrared absorption peaks have been made at roomtemperature. The influence......
