In recent years, NIR-II-type fluorophores with emission wavelengths within the 1000-1700 nm range have garnered widespread attention in field of bioimaging due to their high tissue penetration ability. Here, Mn-doped BaAl2O4, Ba3Al2O6, and Ba7Al2O10 phoshorescence were synthesized by solid-phase or liquid-phase methods. Confirmed XPS EDS analysis, Mn is found uniformly distributed structure valence state +5. The optimal doping concentration Mn5+ three matrices was analyzed PLE PL spectroscopy. addition, samples exhibit a wide excitation spanning from 600 900 nm, coupled narrow band peaking between 1150 1200 nm. As both excellent capabilities biological tissues, fluorescent phosphors this study hold potential for meaningful applications realm fluorescence imaging.

The research on magnetic regulation of manganese oxide systems with strongly correlated electron properties is increasingly active due to rich physical mechanisms and experimental phenomena. Here, Co Cr were used substitute the Mn-site narrow-bandwidth half-doped Pr0.5Ca0.5MnO3 investigate an effective alternative path manipulate magnetism PrMnO3-based manganites. charge-exchange-type charge-ordered state parent material affected significantly differently varying destruction degrees internal spin-ordered caused by two elements. competition between ferromagnetism (FM) double-exchange antiferromagnetism (AFM) super-exchange interactions, which initially existed only in Mn3+/4+-O-Mn3+/4+ bonds, has added Co3+-O-Mn3+/4+/Co3+ Cr3+-O-Mn3+/4+/Cr3+ strength changes various microstructure. dynamic exchange interactions result Co-doped samples developing from FM-AFM coexisting weak FM increase doping content, while Cr-doped evolve ferrimagnetic state. results revealed that different states are attributed differences intrinsic these elements, evolution process originates coexistence multiple interactions. interesting phenomena detailed mechanism analysis contribute modification application oxides.

Many research efforts have focused on designing new inorganic phosphors to meet different application requirements. The structure-photoluminescence relationship between activator ions and the matrix lattice plays an irreparable role in target phosphors. Herein, a series of ABP2O7:Mn2+ (A = Ba/Sr; B Mg/Zn) are prepared for detailed study luminescence performance spatial structure symmetry doping site Mn2+. Due weak interaction nearest B-B pairs, [BO5] is defined as isolated coordination polyhedron whose directly influence photoluminescence emission wavelength Mn2+ ∼620 nm when it occupies triangular bipyramid [MgO5] BaMgP2O7. When quadrangular pyramid-typed or [ZnO5] SrMgP2O7, SrZnP2O7, BaZnP2O7, wavelengths peak at ∼670 nm. We propose conception polyhedral confinement clarify fivefold configuration with geometries, which has great theoretical significance
