“Chemical tuning and band gap engineering of Mn4+ luminescent properties in complex oxides"
The possibility of tuning of luminescent properties including the band gap engineering by adjusting the chemical composition will be demonstrated for the Mn4+-doped Al2O3-Ga2O3 solid solutions and RAlO3 (R = Y, La, Gd, Yb, Lu) perovskites. In particular, spectroscopic features of the Mn4+ deep red emission in Al2O3-Ga2O3 alloys, including the temperature-dependent emission efficiency and decay time, as well as the possibility of their tuning through chemical and hydrostatic pressure will be shown. The possibility of band gap engineering in RAlO3:Mn4+ perovskites in the context of trap depths of intrinsic point defects and their effect on thermoluminescent properties of the material will be demonstrated using both experimental and theoretical approaches.UwagaSeminarium w trybie HybrydowymFaculty of Physics room 0.06link to remote mode:https://zoom.us/j/7218838148szczegóły patrz instrukcja :instrukcja: (pdf file)AttentionThe seminar in the Hybrid modeFaculty of Physics room 0.06for details see instruction :instruction: (pdf file)
