Citric Based Sol-Gel Synthesis and Photoluminescence Properties of Eu³⁺ Doped NaSrBO₃ Phosphors

Abstract:

This paper reports a low-cost NaSrBO3: Eu3+ red phosphor. It was synthesized by sol-gel method. The effects of preparation conditions and doping concentrations on the optical properties were investigated. The structure, photoluminescence properties, thermal stability of Eu3+-doped NaSrBO3 were examined. NaSrBO3: Eu3+ emits a bright red color centered at 611 nm, which originates from5D0-7F2 transition of Eu3+. The PL intensity reaches the maximum at 2at.%. The prepared NaSrBO3: Eu3+ phosphor shows a better thermal stability under high temperature.
