Structure modification and luminescence regulation in new violet light excitable Sr(2-y)BayY4La4(SiO4)6O2:xEu2+ phosphors via cation substitution Cyan-emitting phosphor is urgently needed to address the "cyan gap" in artificial full-spectrum lighting. In this research, a series of Sr(2-y)BayY4La4(SiO4)6O2:xEu2+ (0.005 ≤ x ≤ 0.08, 0.0 ≤ y ≤ 2.0) phosphors with tunable luminescence were synthesized.

Development of a novel Eu2+ activated oxonitridosilicate cyan phosphor for enhancing the color quality of violet-chip-based white LED Cyan phosphor is urgently needed to fill the cyan gap and improve the spectral continuity of white light-emitting diodes (LEDs) to cater to the high criteria for high-quality lighting.
