A polymorphic SrGa2O4:Eu2+ red phosphor for warm illumination and operando visualization of H2O2 catalytic reaction The discovery of multifunctional Eu2+-activated luminescent materials with tailored structure and optical properties can address the specific demands of various application fields. Herein, a polymorphic SrGa2O4:Eu2+ phosphors exhibit temperature-induced phase transformation from γ- to β- phase were fabricated.

Tetrahedrally coordinated rigid crystal structure enables partial self-reduction of mixed-valence europium for optical thermometric application† Zhichao Meng,‡a Yan Gao, ‡*a Ji'an Song,a Zelong Jiang,a Wei Lv,a Qingguang Zeng,a Dawei Wen*a and Tao Hu *a Abstract Mixed-valence europium-activated phosphors are receiving attention in many fields, such as lighting, anti-counterfeiting, optical recording, encryption, and temperature sensing.

Eu2+ Luminescence in CaYGaO4 Olivine: A New Efficient Red Phosphor for Warm Illumination Tao Hu, Zelong Jiang, Bo Wang, Ting Yu, Dawei Wen, Qingguang Zeng and Yan Gao Abstract Fine control of photon emission of Eu2+ activated luminescent materials is essential for advanced optoelectronic applications. However, it remains difficulty to design blue light excitable Eu2+ doped oxide red phosphor due to ionicity of the oxide ions.
