Chasing Down the Eu 2+ Ions: The Delicate Structure−Property Relationships in the Ultra‐Narrow Band Phosphor K 1.6 Na 2.1 Li 0.3 [Li 3 SiO 4 ] 4 :Eu 2

Chasing Down the Eu 2+ Ions: The Delicate Structure−Property Relationships in the Ultra‐Narrow Band Phosphor K 1.6 Na 2.1 Li 0.3 [Li 3 SiO 4 ] 4 :Eu 2

Eu 2+ ‐activated phosphors of the UCr 4 C 4 structure type have emerged as promising new (ultra‐)narrow band phosphors. Especially the UCr 4 C 4 ‐type alkali lithosilicates have caused a sensation in the field of phosphor research in the recent years due to their consistent (ultra)narrow‐band lumine...

Zusammenfassung:Eu 2+ ‐activated phosphors of the UCr 4 C 4 structure type have emerged as promising new (ultra‐)narrow band phosphors. Especially the UCr 4 C 4 ‐type alkali lithosilicates have caused a sensation in the field of phosphor research in the recent years due to their consistent (ultra)narrow‐band luminescence in the cyan and green range that can pave the way to novel backlighting LEDs with high color gamut. The compound “K 2 Na 2 [Li 3 SiO 4 ] 4 :Eu 2+ ” stands out with a strikingly narrow emission in the cyan range (
