英文摘要: Novel Ce3+-doped SrSc2O4 phosphors were synthesized via a solid state method. The crystal structure and morphology were characterized by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The photoluminescence properties, quantum efficiency, CIE value and thermal stability of SrSc2O4:Ce3+ phosphors were investigated in detail to evaluate their application in LEDs. The photoluminescence results revealed that the phosphors have an excitation band in the blue region from 400 to 470 nm and a broad green emission band peaking at about 491 nm. The above results indicated that the phosphors can be effectively excited by blue light and could be promising candidates as green-emitting phosphors for application in LEDs.
