Luminescence properties of Sr3−x−3y/2MxCeyAlO4F (M=Ca, Ba, 0≤x≤0.9, 0.001≤y≤0.05) phosphors

► Blue and green emitting oxyfluoride phosphors are excitated near 410 nm ► Ce3+-activated oxyfluoride phosphors are quite effective to prepare white light for near-UV LED applications. ► Gradual substitution of Ce3+ content in the oxyfluoride hosts changes CIE values.
