摘要: Abstract Single‐phase KL aSr3 (PO 4) 3F: Sm3+ phosphors with fluorapatite structure were prepared via high‐temperature solid‐state method in air atmosphere for the first time. The X‐ray diffraction, scanning electron microscope, diffuse reflectance spectra, photoluminescence spectra, and temperature‐dependent emission spectra, as well as lifetimes were measured to characterize the as‐prepared phosphors. Phase results indicated that KL aSr3 (PO 4) 3F: Sm3+ belongs to hexagonal system with a space group of …
