Department of Chemistry, Government College, Burner, Barmer-344 001 Manuscript received 11 October 1982, revised 26 May 1986, accepted 18 June 1986 The mixed-ligand complexes of InIII with L-glutamate and L-methionine/L-valise/ L-proline have been investigated by polarographic technique. The cathodic reduction of mixed complexes involved three electrons, reversible and diffusion-controlled step. The logarthmic values of over all formation constants of In(L-glutamate)(L-methinninate), In(L-glutamate)(L-valinate) and In(L-glutamate)(L-prolinate) complexes were 16.78, 17.19 and 18 00, respectively. The positive values of logritham of mixing constant revealed that the mixed complexes were more stable than the parentbiscomplexes.
10 pags., 3 figs., 4 tabs. ; We present angle-integrated and angle-differential cross sections for electron-impact excitation of the (5s25p)P1/22→(5s26s)S1/22 transition in atomic indium. Experimental data for six incident electron energies between 10 and 100 eV are compared with predictions from semirelativistic and fully relativistic B-spline R-matrix calculations, as well as a fully relativistic convergent close-coupling model. Agreement between our measured and calculated data is, with a few exceptions, found to be typically very good. Additionally, the agreement between the present theoretical predictions is generally excellent, with the remaining small deviations being associated with the slightly different, although still very accurate, descriptions of the target structure. Agreement between the present results and an earlier relativistic distorted-wave computation [T. Das, R. Srivastava, and A. D. Stauffer, Phys. Lett. A 375, 568 (2011)PYLAAG0375-960110.1016/j.physleta.2010.12.037] was, however, found to be marginal, particularly at 10 and 20 eV. ; The work of K.R.H., O.Z., and K.B. was supported by the U.S. National Science Foundation under Grants No. OAC1834740 and No. PHY-1803844, and by the XSEDE supercomputer allocation Grant No. PHY-090031.

The authors report the enhancement of hole injection using an indium tin oxide (ITO) anode covered with ultraviolet (UV) ozone-treated Ag nanodots for fac tris (2-phenylpyridine) iridium Ir(ppy)3-doped phosphorescent organic light-emitting diodes (OLEDs). X-ray photoelectron spectroscopy and UV-visible spectrometer analysis exhibit that UV-ozone treatment of the Ag nanodots dispersed on the ITO anode leads to formation of Ag2O nanodots with high work function and high transparency. Phosphorescent OLEDs fabricated on the Ag2O nanodot-dispersed ITO anode showed a lower turn-on voltage and higher luminescence than those of OLEDs prepared with a commercial ITO anode. It was thought that, as Ag nanodots changed to Ag2O nanodots by UV-ozone treatment, the decrease of the energy barrier height led to the enhancement of hole injection in the phosphorescent OLEDs. ; This work was supported by Korea Research Foundation grant funded by Korean Government (MOEHRD: Basic Research Promotion Fund)(KRF-2006-003-D00243) and Ministry of Commerce, Industry, and Energy.
