A thermally stable narrow-band green-emitting phosphor MgAl2O4:Mn2+for wide color gamut backlight display application

A stable narrow-band green phosphor MgAl₂O₄:Mn²⁺peaking at 525 nm with a full-width at half-maximum of 35 nm and a quantum efficiency of 45% upon 450 nm blue-light excitation is demonstrated, and which has good promising for wide color gamut backlight display.
