Abstract
The spectral and kinetic characteristics of BaY2F8 crystals with coactivation by Tb–Yb ions under excitation at a wavelength of 266 nm were studied. Luminescence of Yb3+ ions was detected in the NIR spectral range because of charge transfer processes. Studies at low-temperature have not shown the cooperative energy transfer, as well as single-photon processes of direct energy transfer to acceptor ions have been found. The quantum yields were measured, taking values of 70.3, 49.3, and 55.05% for 2, 5, and 10 at % ytterbium ion concentrations, respectively.
期刊介绍：
Bulletin of the Russian Academy of Sciences: Physics is an international peer reviewed journal published with the participation of the Russian Academy of Sciences. It presents full-text articles (regular, letters to the editor, reviews) with the most recent results in miscellaneous fields of physics and astronomy: nuclear physics, cosmic rays, condensed matter physics, plasma physics, optics and photonics, nanotechnologies, solar and astrophysics, physical applications in material sciences, life sciences, etc. Bulletin of the Russian Academy of Sciences: Physics focuses on the most relevant multidisciplinary topics in natural sciences, both fundamental and applied. Manuscripts can be submitted in Russian and English languages and are subject to peer review. Accepted articles are usually combined in thematic issues on certain topics according to the journal editorial policy. Authors featured in the journal represent renowned scientific laboratories and institutes from different countries, including large international collaborations. There are globally recognized researchers among the authors: Nobel laureates and recipients of other awards, and members of national academies of sciences and international scientific societies.
