Abstract

For the first time blue up-conversion emission from U⁴⁺ (5f²)-ion doped into a Cs₂ZrCl₆ single crystal under green light (19436 cm^-1) excitation has been observed and characterized. Five, blue emission bands, centered at 19780, 20010, and 20280 cm^-1 for the ¹I₆→³H₄ U⁴⁺-transitions and at 20700 and 20970 cm^-1 for the ³P₂→³H₄ U⁴⁺-transitions, have been observed. This up-conversion process involves a two-photon absorption. Fluorescence efficiencies of 8.78 × 10^-4 and 4.20 × 10^-5 have been estimated for the ¹I₆→³H₄ (19780, 20010 and 20280 cm^-1) and the ³P₂→³H₄ (20700 and 20970 cm^-1) emissions in U⁴⁺-ion, respectively, at room temperature for the sample doped with 1 wt% UCl₄. An up-conversion mechanism is proposed.
