ABSTRACT:
The delayed fluorescence observable with tantalate phosphors is decreased by the use of a flux composition consisting essentially of 2-95% by weight KCl, 5-98% by weight of at least one lithium salt chosen from a group consisting of LiCl and Li.sub.2 SO.sub.4 and 0-50% by weight of SrCl.sub.2.
