The color-tunable emissions of Dy3+-activated SrLaMgTaO6 phosphors were synthesized via a conventional high temperature solid-state reaction method. The phase and the luminescent properties were well characterized by X-ray diffraction patterns (XRD), diffuse reflectance spectra, luminescent spectra and lifetime. The XRD result revealed the as-prepared samples exhibited a monoclinic structure with...
A narrow high intensity red-emitting double-perovskite type phosphor SrLa1−xMgTaO6:xEu3+ was successfully synthesized by a solid-state reaction method. Under the excitation of the near UV and blue light, this phosphor exhibited intense red emission that can improve the color qualities of warm light-emitting diodes. Due to the Eu3+ ions being an intrinsically asymmetric cation environment, the dominant...
