Cool green-emissive Y2Si2O7:Tb3+ nanophosphor: auto-combustion synthesis and structural and photoluminescence characteristics with good thermal stability for lighting applications

“…[9][10][11][12][13] Generally, commercial wLEDs are typically produced by coalescing blue-emanating InGaN-chips with yellow-emitting Y 3 Al 5 O 12 :Ce 3+ nanophosphors. 14,15 However, these WLEDs oen lack a red module in the visible range, resulting in a white emission with a subpar color-renderingindex and high correlated-color-temperature. 16 To address this issue, an alternative approach involves coating primary red, green, and blue nanophosphors onto a NUV-LED chip, aiming to achieve WLEDs with high rendering-index, proper CCT and adjustable color characteristics.…”
