Abstract

The intrinsic green-emitting Sr₂Sb₂O₇ phosphors with an orthorhombic structure were synthesized. Meanwhile, the doping of Bi³⁺ ions greatly enhanced the luminescent properties of Sr₂Sb₂O₇ material by increasing the particle size and supplying the ³P₁ → ¹S₀ emission. The strong green-emitting Sr₂Sb₂O₇:Bi³⁺ phosphors with excellent moisture resistance and structural stability can be used for some practical applications. The packaged light-emitting diode (LED) devices based on the Sr₂Sb₂O₇:Bi³⁺ phosphors with and without commercial phosphors were fabricated. Practically, the white LED device exhibited a warm white emission with the color rendering index and correlated color temperature values of 85.36 and 4185 K, respectively. Besides, the Sr₂Sb₂O₇:Bi³⁺ security inks with good water resistance were presented. Finally, the prepared materials have also been successfully applied to latent fingerprint detections and flexible films. Therefore, these strong green-emitting materials are suitable for various optical applications.
