Synthesis and photoluminescence properties of Li3ScBr6:Ce phosphor are described. The phosphor was synthesized by a simple wet-chemical method. Lithium carbonate and Scandium oxide in stoichiometric proportions were dissolved in HBr. Activator was added in form of oxalate salt. After evaporating the solution to dryness the phosphor powder was obtained. Strong ultraviolet emission was observed for this phosphor. The UV emission is typical of Ce 3+ . It consists of a 359 nm band having a component at about 340 nm. The excitation spectrum has the most intense band at 314 nm besides smaller bands/shoulders around 255, 280 and 335 nm.
