Abstract
The present disclosure relates to luminescent phosphors and more particularly, to fluoride-based luminescent phosphors, and methods for their preparation in deep eutectic solvent (DES) systems. The luminescent phosphors are formed with accompanying particle size control, relatively higher crystallinity and relatively higher fluorescence intensity.
