Abstract

Er3+/Eu3+/Yb3+:NaZnPO4 nanophosphors synthesized using the co-precipitation technique are structurally and optically characterized. The effect of the Eu3+ ion concentration on the photoluminescence (PL) emission intensity and the energy transfer mechanisms implicated in the nanophosphors presented is discussed. The red to green intensity ratio, quantum yield and asymmetry ratio are calculated. The Eu–O ligand behaviour and spectral characteristics are explained in the light of the nephelauxetic ratio and the Judd–Ofelt parameters. A maximum sensitivity of ∼7.3 × 10−3 K−1 at 503 K and the optical heating behaviour with the incorporation of Eu3+ ions in the Er3+–Yb3+:NaZnPO4 nanophosphors are reported.
