Trapping effects in CdSiO3:Jn3+ long afterglow phosphor based on photoluminescence (PL) and thermoluminescence (TL) curves are studied. The results of TL show t
The electronic structure of the new superconductor SmO1-xFxFeAs (x = 0.15) is studied by angle-integrated photoemission spectroscopy. Our data show a sharp feat
A novel photovoltaic cell with an active layer of poly(phenyleneethynylene)(PPE)/C60/N,N-diphenyl-N,N-di-(m-tolyl)-p-benzidine(TPD)is designed.In the active lay
We investigate the third-order nonlinear absorption and dispersion of femto- and atto-second polarization beats between the one-photon degenerate four-wave mixi
We study the generation of an entangled motional coherent state of two distant ions trapped in two cascadedc avities, in which the motional mode of the each ion
We have demonstrated passive mode-locking in a diode-end-pumped Nd:YVO4 laser using two kinds of semiconductor absorbers whose relaxation region comes from In0.
