Red emitting Eu3+ doped Sr3La2(BO3)4 phosphors for LED and anti-counterfeiting applications

A series of Eu 3 + -activated Sr 3 La 2 (BO 3 ) 4 (SLB) orange-red phosphors were synthesized via a high-temperature solid-state method. Under 394 nm excitation, the optimal phosphor exhibits orange-red emission with a dominant peak at 612 nm ( 5 D 0 → 7 F 2 ) and a color purity...
