2.The absorption spectra indicate that the adsorption of dithiooxamide on the silver nanoparticles results in a red-shift in the SPR band, mainly caused by the changes in the microenvironment of the metal nanoparticles and charge density alteration due to the charge transfer between the molecules and metal particles.
3.The results of UV spectra showed that all ofthese bis-cyclometalated complexes had intense absorption peaks吴忠联:环金属铱配合物的合成及其电磷光器件的性能研究from metal-to-ligand charge transfer(MLCT) transitions, whichindicates these Ir-complexes should be used as two serious of novelelectrophosphorescent materials.
6.The advance, the applications in organic light-emitting diodes (OLEDs) and the future R&D directions of the well developed types of organic red emitters, such as transition metal complexes, intra-molecular charge transfer (ICT) compounds, condensed aromatic hydrocarbons and oligomers are discussed.
7.An adsorption study on bensulfuron-methyl (BSM) on three synthsized metal oxides and two variable charge soils, and the effects of pH, metal ion Zn2+ on tested samples, have been carried out. The characteristics of adsorption kinetics have been investigated using the static, stirred and vortex batch techniques for GZ-soil (Guangzhou Soil), HN-soil (Hunan Soil) and Al oxide.
8.In this article the stabilization energy of mononuclear and binuclear transition-metal dinitrogen complexes, in which the charge density on the atoms of N_2 coordinated to the metal center in "end-on" or"side-on" form, are calculated respectively by using the methods of HMO and graph theory. The results of calculation are compared and used to explain some facts inexperiments.
