摘要

这项研究分析了六种 Eu2+激活的硫代镓酸盐的晶体结构特性和光致发光特性：CaGa2S4:Eu2+、SrGa2S4:Eu2+、EuGa2S4、BaGa2S4:Eu2+、Sr2Ga2S5:Eu2+和Eu2Ga2S5。研究讨论了光致发光参数，如吸收能量 (Eabs)、发射能量 (Eem)、零声子线能量 (E0)、斯托克斯位移 (ΔS) 和红移 (D)。这是首次报道这六种 Eu2+ 活化硫代镓酸盐的光致发光参数，因此提供了有关这些材料的重要信息。

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 (E_abs), emission energy (E_em), 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.
