Deep red BaTiF4:Mn4+ phosphor: synthesis, optical properties and application for warm WLED devices

Photoluminescence properties of a novel red fluoride K2LiGaF6:Mn4+nanophosphor

“…31-38 and BMF 6 :Mn 4+ (B ¼ Ba, Zn, M ¼ Si, Ti, Ge) [39][40][41][42][43][44][45] were reported. Some of them show high quantum efficiency, thermal stability against quenching and so on.…”

A novel Mn4+-activated fluoride red phosphor Cs30(Nb2O2F9)9(OH)3·H2O:Mn4+ with good waterproof stability for WLEDs

“…[1][2][3][4][5] The combination of the yellow-emitting Y 3 Al 5 O 12 :Ce 3+ (YAG:Ce 3+ ) phosphor and blue-light InGaN LED chip is a classical approach for manufacturing WLEDs, [6][7][8][9] however, the CRI is usually too low (below 80) and the CCT is too high (6000 K to 8000 K) for indoor lighting. [10][11][12] For the purpose of further enhancing the application performance of WLEDs, especially to promote the CRI and lower the CCT value, the introduction of red-light-emitting particles as a supplementary material [13][14][15][16] has gathered long-standing consideration.…”
