We report the excited-state upconversion in Pr(0.5)Yb(1.5):ZBLAN under two-colour excitation of 960nm laser and xenon lamp light.Three obvious upconversion exci
Based on total variance of a pair of Einstein-Podolsky-Rosen (EPR) type operators, the generalized EPR entangled states in continuous variable systems are defin
We investigate the polarized emission behaviour of an Eu3+ doped azo-polymer waveguide. Affected by the azobenzene groups in the photoinduced orientation proces
Single-electron detachment (SED) cross sections for Cr- and Ti- in collision with N2 have been obtained in the energy region of 10-30 ke V, for the first time
