Abstract(in English) | In this study, we investigated the oxidation fluoride sulfide-based matrix material for the purpose of implementation of near-ultraviolet to blue excitation with charge transfer state(CTS) excitation band by the combination of anion elements. As a result, we confirmed that the valence of Eu ions are incorporated into the matrix by the degree of ionic-covalent changes. The light emission characteristics from Eu substituted on two different La sites from La_3OF_3S_2:Eu are respectively obtained, and absorption seems to be due to CTS was observed at around 400~500nm. |
