Discovery of a novel rare-earth free narrow-band blue-emitting phosphor Y3Al2Ga3O12:Bi3+with strong NUV excitation for LCD LED backlights

Herein, an emerging no-rare earth doped and narrow-band blue-emitting phosphor of Y₃Al₂Ga₃O₁₂: Bi³⁺with narrow-band blue emission peaking at 410 nm with FWHM of 39 nm, is pioneeringly developedviaselective excitation.
