Sm3+ Doped Lithium Strontium Borate Glasses for Solid State Lighting Applications

Facile route for synthesis of strontium hexaborate crystalline powders

“…The peaks at 223 and 364 cm −1 correspond to bending modes of the tetrahedral borate anionic groups (BO 4 ). The very intense peak 555 cm −1 distributes to stretching vibrations of B–O–B in BO 3 14,25 …”

“…The peaks 770 and 919 cm −1 are stretching vibrations of B–O in tetrahedral borate (BO 4 ) 14 . The peaks 1245 and 1366 cm −1 relate to asymmetric stretching vibrations of BO 3 groups 14 .…”

“…Among host materials, the crystalline powders of strontium borates are special phosphors with potential applications. As a result, strontium borates and their derivatives have emerged as a new class of luminophore hosts in recent years 9–15 . Strontium borates can be doped with lanthanide ions.…”

“…As a result, strontium borates and their derivatives have emerged as a new class of luminophore hosts in recent years. [9][10][11][12][13][14][15] Strontium borates can be doped with lanthanide ions. Their energy level is 1 S 0 (4f 2 ) located below the lowest 4f 1 5d energy level.…”
