- Abstract
The ultraviolet (UV)-emitting SrPO:Ce phosphors were synthesized via the solid-state reaction method, and their structural, morphological and luminescence properties were characterized by X-ray diffraction analysis, scanning electron microscopy, photoluminescence spectroscopy. The obtained results indicate that these phosphors can be effectively excited by short-wavelength ultraviolet (<300 nm), and exhibit long-wavelength ultraviolet (300-380 nm) emission with nanosecond-level fluorescence lifetime corresponding to the parity-allowed 5d-4f transitions of Ce. The concentration-quenching phenomenon of Ce in SrPO host was also studied, in which the critical energy transfer distance between Ce ions and concentration quenching mechanism were determined.
