Photoluminescence properties of Eu2+-activated thiogallate phosphors
This work analyzes the crystal structural properties and photoluminescence properties of six Eu2+-activated thiogallates: CaGa2S4:Eu2+, SrGa2S4:Eu2+, EuGa2S4, BaGa2S4:Eu2+, Sr2Ga2S5:Eu2+, and Eu2Ga2S5. Photoluminescence parameters such as the absorption energy (Eabs), emission energy (Eem), zero-phonon line energy (E0), Stokes shift (ΔS), and red shift (D) are discussed. This work is the first report on the photoluminescence parameters of these six Eu2+-activated thiogallates and therefore provides important information about these materials.
