UV‐excited blue‐ to green‐emitting Tb3+‐activated sodium calcium metasilicate colour tunable phosphor for luminescence devices

“…Despite the availability of numerous oxide hosts, such as borates, phosphates, tungstates, molybdates, and vanadates, the silicates were the preferential choice as they have good physical–thermal–chemical stability with a wide band gap and a low thermal expansion coefficient. [ 17–19 ]…”

“…Despite the availability of numerous oxide hosts, such as borates, phosphates, tungstates, molybdates, and vanadates, the silicates were the preferential choice as they have good physicalthermal-chemical stability with a wide band gap and a low thermal expansion coefficient. [17][18][19] However, silicates are the most abundant option in nature and are categorized as ortho (1:4), meta (1:3) and pyro (2:7) depending upon the Si:O ratio. [20] Amongst various metasilicates, Na 4 Ca 4 Si 6 O 18 occurs as a ternary compound in the Na 2 O-CaO-SiO 2 system.…”
