Highly efficient narrowband blue-emitting CsCl: Eu ²⁺ films toward wide-gamut displays

This is the authors' abstract. We don't add key points for this paper.

Micron-sized CsCl: Eu 2+ films synthesized using DI water at low temperatures, exhibiting strong blue photoluminescence peak at ∼442 nm with PLQY of ∼81% and FWHM of ∼29.4 nm.
