Electronic Structure Calculation of Cr3+ and Fe3+ in Phosphor Host Materials Based on Relaxed Structures by Molecular Dynamics Simulation

Autor: Joichiro Ichikawa, Hiroko Kominami, Kazuhiko Hara, Masato Kakihana, Yuta Matsushima

Publikováno v: Technologies, Vol 10, Iss 3, p 56 (2022)

The electronic structures of the luminescent center ions Cr3+ and Fe3+ in the deep red phosphors LiAl5O8:Cr3+, α-Al2O3:Cr3+, and γ-LiAlO2:Fe3+ were calculated by the DV-Xα method, in which the local distortion induced by the replacement of Al3+ si

Solvothermal Synthesis of YF3:Ce3+ Nanophosphors for Medical Applications

Autor: Arira Fujii, Hiroko Kominami, Vadim V. Bakhmetyev, Anastasiia M. Dorokhina, Maxim М. Sychov

Publikováno v: Materials Science Forum. 1040:55-60

In this paper, the time effect of hydrothermal synthesis on YF3 morphology particles is considered. The work was carried out on X-ray-excited YF3:Ce3+ phosphors. The synthesis was carried out by the hydrothermal method, since it avoids high temperatu
