In the dual-emitting Eu3+-activated Sr2NaMg2V3O12 garnet, vibrationally induced thermometric response and thermochromic luminescence are investigated for first time. Based on diverse thermal quenching of VO43? Eu3+ along with advantage variation in fluorescence intensity ratio, a potential phosphor sensitive dual-mode ratiometric colorimetric temperature sensors is proposed which maximum absolu...

In this study, 1,10-phenanthroline molecules were introduced in the interlayer space of a paramagnetic synthetic saponite clay containing both Eu3+ and Gd3+ ions structural positions. Two samples with different loading phenanthroline dye prepared. The resulting hybrid materials possessed improved optical emission properties due to an efficient antenna effect from centers; was demonstrated be hi...

In this study, Eu-doped CdSe nanoparticles with variable Eu3+ content were synthesized by a simple sonochemical method. Eu3+ substitution into the structure of CdSe resulted in a material with new physical properties, composition and morphology. The synthesized nanoparticles were characterized by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscop...

A series of 18 lanthanide-containing 1D-coordination polymers 1∞[Ln2(2–PyPzH)4Cl6], Ln = La, Nd, Sm, dinuclear polymorphic complexes α–, β–[Ln2(2–PyPzH)4Cl6], Eu, Gd, α–[Tb2(2–PyPzH)4Cl6], and [Gd2(2–PyPzH)3(2–PyPz)Cl5], mononuclear [Ce(2–PyPzH)3Cl3], [Ln(2–PyPzH)2Cl3], Tb, Dy, Ho, Er, salt-like [Gd3(2–PyPzH)8Cl8]Cl [PyH][Tb(2–PyPzH)2Cl4] were obtained from the reaction respective lanthanide ch...

Eu3+-doped Ba3MgSi2O8 has attracted much attention for the photochromic behavior. It been suggested that this behavior originates from photoinduced electron defects. In study, defects induced in silicate were discussed spectroscopic similarity between Ba3MgSi2O8: Eu3+ and isostructural K3Na(SO4)2. ESR spectra measured a single-crystalline K3Na(SO4)2, orientation of which was determined by Raman...

Eu-doped periodic mesoporous organosilicate (PMO) films with terminal methyl and ethylene bridging groups have been synthesized using sol-gel technology spin-coating, employing evaporation-induced self-assembly (EISA), on silicon wafers. Eu doping is achieved by the dissolution of Eu(NO3)3·6H2O in precursor solution. The deposited are characterized Fourier transform infrared (FTIR) spectroscopy...

BaGa2O4 ceramics doped with Eu3+ ions (1, 3 and 4 mol.%) were obtained by solid-phase sintering. The phase composition microstructural features of investigated using X-ray diffraction scanning electron microscopy in comparison energy-dispersive methods. Here, it is shown that undoped Eu3+-doped are characterized a developed structure grains, grain boundaries pores. Additional phases mainly loca...
