Solution-based synthesis of BaAl 2 S 4 was developed for the first time. This blue emission phosphor was synthesized by sulfurization-reduction of the fine oxide precursor prepared by the polymerizable complex method. The proposed technique does not require handling of samples in the glovebox or annealing in evacuated ampoules.
