Several alkaline earth sulfides doped with Eu2+ and Er3+ ions have been synthesized and shown to be potential phosphors for applications in the visible spectral range. The excitation and emission spectra corresponding to the 4f–5d interconfigurational transitions of Eu2+ were analyzed with an aim of extraction of the main parameters of the electron-vibrational interaction. The values of the Huang–Rhys...
A series of triphenylamine-based chromophores (L1–3) with donor-π-donor (D-π-D) model have been designed and synthesized via solid phase Wittig reaction. Their one/two-photon fluorescence and electrochemical properties have been investigated. The results show that L2 and L3 exhibited strong and wide-dispersed two-photon-excited fluorescence (TPEF) in different solvents. Chromophore L3 displays the...
