High‐Efficiency Cyan–Green‐Emitting Y3Sc2Ga3O12:Ce Phosphor for Microcrystals and Ultrathin Phosphor‐Glass Composite for Light‐Emitting Diode

“…However, the white light generated using this technique suffers from several issues, such as insufficient color-rendering index (CRI, < 80) and high correlated color temperature (CCT, > 4500 K), [9−12] which primarily stems from the insufficient emission in the cyan and red spectral regions. Although the advancement of high-efficiency red phosphors, such as CaAlSiN 3 :Eu 2+ , K 2 SiF 6 :Mn 4+ , and Sr 2 Si 5 N 8 :Eu 2+ , has greatly enhanced the CRI of WLED devices to ≈90, [13][14][15][16][17][18] a tradeoff occurs with the decrease in the luminous efficiency owing to the absence of a cyan emission. [19] Thus, the development of efficient cyan-emitting phosphors is highly desirable to achieve full-spectrum sunlightresembling illumination.…”
