Cyan, deep red and white light emission generated by SrLaGa3O7:Bi3+, SrLaGa3O7:Mn4+ and SrLaGa3O7:Bi3+/Mn4+ phosphors

Zhi-Jian Li et al.

Summary: The crystal structures, composition, and optical properties of Bi3+-doped, Mn4+-doped, and Bi3+/Mn4+ co-doped SrLaGa3O7 (SLGO) phosphors were investigated. The synthesized phosphors can be excited by ultraviolet and near ultraviolet light, with emissions that can be tuned by changing excitation wavelength and dopant concentrations. Energy transfer from Bi3+ to Mn4+ was observed in the co-doped phosphors, suggesting potential applications in warm white LED lighting.

Novel broadband near-infrared emitting long afterglow phosphor MgGeO3: Cr3+

Guna Doke et al.

Summary: In this study, the broadband near-infrared persistent luminescence of a novel MgGeO3: Cr3+ material is reported. The luminescence can be excited by ultraviolet radiation and detected for more than 16 hours. The interaction between Cr3+ luminescence centers, oxygen-impurity complexes, and oxygen vacancy related trapping states is suggested as the cause of the observed bands. The study also reveals that athermal tunnelling directly to the luminescence centers is the main detrapping route for the trapped charge carriers in the MgGeO3: Cr3+ material. This research contributes to a better understanding of the luminescence mechanism of the material.

Structural elucidation of hexavalent Cr adsorbed on surfaces and bulks of Fe3O4 and α-FeOOH

Nichapha Senamart et al.

Summary: Magnetite and goethite were synthesized and used as adsorbents for Cr6+ removal. The adsorption isotherms fit the Langmuir model, indicating monolayer adsorption. XAS and XPS analysis confirmed the production of stable Cr3+ species during Cr6+ reduction and migration. The presence of physisorbed FeO-HCrO4 reduced the reducibility and adsorption capability of Cr6+.

Synthesis and characterization of a near-infrared persistent luminescent Cr-doped zinc gallate-calcium phosphate composite

Wai-Tung Shiu et al.

Summary: Near-infrared emitting persistent luminescence nanoparticles have attracted attention for bioimaging and biosensing applications. In this study, a drug carrier with persistent luminescence properties was designed by forming a composite of Cr-doped zinc gallate and amorphous calcium phosphate. The composite retained the persistent luminescence properties of Cr-doped zinc gallate, and the migration of Zn2+ from the composite led to different luminescence mechanisms compared to pure Cr-doped zinc gallate.
