N2 - 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.
