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.
