Abstract
Cu+-doped Na5Ca4(PO4)4F fluorophosphate was synthesized by wet-chemical method. This blue-emitting phosphor was characterized by XRD, FTIR and photoluminescence measurements. Rietveld refinement method was employed to analyse the phase formation of the as-prepared phosphor. The electron-vibrational interaction (EVI) parameters were calculated by the spectrum-fitting method. Na2Ca4(PO4)3F:Cu+ phosphor demonstrated blue emission under near-UV excitation and its CIE coordinates were found at (0.151, 0.037).
