Crystal field splitting of the 4f 5d electronic configuration of Pr 3+ ions in wide band gap fluoride dielectric crystals

Sarantopoulou E.; Kollia Z.; Cefalas A.; Semashko V.; Abdulsabirov R.; Naumov A.; Korableva S.; Szczurek T.; Kobe S.; McGuiness P. (2002)

The absorption and the laser-induced fluorescence spectra of Pr 3+ ion in YF3 , LaF3 , KY3 F 10 and LiLuF4 , single crystal hosts were obtained in the vacuum ultraviolet region of the spectrum. The energy position and the ...
Down-conversion luminescence of Yb<sup>3+</sup> in novel Ba<inf>4</inf>Y<inf>3</inf>F<inf>17</inf>:Yb:Ce solid solution by excitation of Ce<sup>3+</sup> in UV spectral range

Nizamutdinov A.S.; Kuznetsov S.V.; Madirov E.I.; Voronov V.V.; Khadiev A.R.; Yapryntsev A.D.; Ivanov V.K.; Semashko V.V.; Fedorov P.P. (2020)

© 2020 Elsevier B.V. The down-conversion luminescence under UV excitation was demonstrated in single-phase Ba4Y3F17 solid solution nanoparticles codoped with Ce3+/Yb3+. The complex photodynamic processes occurred in the ...
Impurity segregation coefficient measurements in LiF-LuF 3-YF3 systems doped by Nd3+

Marisov M.; Koryakina E.; Naumov A.; Semashko V.; Korableva S.; Ivoilov N. (2011)

In present work the results of measurements of segregation coefficient of Nd3+ ions in LiLuxY1-xF4 (x=0- 1) crystals are presented. Two methods for Nd3+ ions concentration measurements in the crystals are used. The first ...
