Abstract

The blue emission from U⁴⁺(5f²) ion doped into a Cs₂ZrCl₆ single crystal under green light (19,436 cm^-1) excitation has been observed and characterized. Five blue emission bands for the intra 5f¹I₆ → ³ H₄ (19,700, 20,010, and 20,280 cm^-1) and ³P₂ → ³H₄ (20,700 and 20,970 cm^-1) U⁴⁺ transitions have been observed. The up-conversion efficiencies for the ¹I₆ and ³P₂ emissions have been estimated as a function of temperature; that for ³P₂ emission increases with increasing temperature. We suggest that this result is due to an increasing population of the ³P₂ level caused by thermal excitation of U⁴⁺ ions in the ¹I₆ level.
