Abstract
Eu3+ doped NaLi2PO4 red luminescent phosphor has been synthesized by solid state reaction and its phase purity has been confirmed by X-ray diffraction analysis. Optical properties of the phosphor have been investigated and the effect of dopant (Eu3+) concentration (0.1–3.0 mol%) has been observed. Excitation spectra of the phosphor NaLi2PO4:Eu3+ show a very efficient absorbance band corresponding to the common allowed transition 7 F 0 → 5 L 6 occurring at 393 nm, while the luminescence spectra exhibit prominent emission peak centered at 702 nm (5 D 0 → 7 F 4) in pure red region. Color purity of this red phosphor has been calculated and found to be around 99.9 %, which is very close to that of commercial red phosphor Y2O3:Eu3+. Luminescence studies of the phosphor show excellent stability with respect to excitation energy. Chromatic investigations have also been performed using emission spectrum and some important chromatic parameters are calculated using CIE-1931 color calculator in order to find potential application of the phosphor.
