Special Issue Information

Dear Collegues,

Lanthanide complexes hybridized with organic components are recently attracted much attention for the next material sciences, because of their characteristic electron configuration localized on f-orbitals. The development and syntheses also provide stable colored luminescence, unleashed magnetism including single molecular magnetic behaviors, and upconverting materials under the well- designed molecules. Lanthanides also called as Rare Earths are also focused as noble metal sources in nature, but there is nothing else such metals instead of their unique electron configuration of lanthanides. The coordination chemistry with lanthanide ions is one of the techniques the establish of efficient advanced materials with saving the amount of lanthanide used. Recently, theoretical results also performed to expect new coordination chemistry in lanthanides combined with experimental measurements and aspects.

This Special Issue, “Advances of Lanthanide Complexes”, will be a collection of full papers, short communications and review papers focusing on latest progress in the field of fundamental aspects and applications, and will inspire researchers for the future materials with lanthanides. Finally, the Special Issue is to be a platform for lanthanide complex researchers from the experimental and theoretical approaches.

Electrochemical switching of luminescence color between magenta and blue using two types of luminescent materials and electrochromic molecules was demonstrated based on the control of excited energy transfer through an electrochromic reaction. The magenta photoluminescence, due to the integration of red luminescence from the Eu(III) complex and blue fluorescence from the anthracene derivative, was reversibly modulated to a pure-blue luminescence color by an electrochemical redox reaction. Electrofluorochromism is induced by effective excited energy transfer from the Eu(III) complex to the electrochromic molecule under a redox reaction. Full article

The atomic structure of antiphase boundaries in Sr-doped lanthanum scandate (La1−xSrxScO3−δ) perovskite, promising as the proton conductor, was modelled by means of DFT method. Two structural types of interfaces formed by structural octahedral coupling were constructed: edge- and face-shared. The energetic stability of these two interfaces was investigated. The mechanisms of oxygen vacancy formation and migration in both types of interfaces were modelled. It was shown that both interfaces are structurally stable and facilitate oxygen ionic migration. Oxygen vacancy formation energy in interfaces is lower than that in the regular structure, which favours the oxygen vacancy segregation within such interfaces. The calculated energy profile suggests that both types of interfaces are advantageous for oxygen ion migration in the material. Full article

The results of the calculation of the energy band structure and luminescent research of CeF3 crystals are presented. The existence of two 5d1 and 5d2 subbands of the conduction band genetically derived from 5d states of Ce3+ ions with different effective electron masses of 4.9 me and 0.9 me, respectively, is revealed. The large electron effective mass in the 5d1 subband facilitates the localization of electronic excitations forming the 4f-5d cerium Frenkel self-trapped excitons responsible for the CeF3 luminescence. The structure of the excitation spectra of the exciton luminescence peaked at 290 nm, and the defect luminescence at 340 nm confirms the aforementioned calculated features of the conduction band of CeF3 crystals. The peculiarities of the excitation spectra of the luminescence of CaF2:Ce crystals dependent on the cerium concentration are considered with respect to the phase formation possibility of CeF3.
