[Display omitted] • Polycrystalline ZrTe 3 O 8 :2%Er,3%Mn was prepared by solid-state reaction technique. • The structure is described by disphonoids (TeO 4 E) and octahedron of ZrO 6. • The ZrTe 3 O 8 :2%Er, 3%Mn exhibits an important emission in the visible and near-infrared domains. • Raman spectrum showed a weak band at 450 cm−1 and an intense band at 840 cm−1. • Magnetic analysis revealed that our sample exhibited a PM - FM transition below 5 K. Polycrystalline ZrTe 3 O 8 :2%Er, 3%Mn was prepared by the solid-state reaction technique. The formation of single-phase material was determined by X-ray diffraction studies and found to be a cubic phase at room temperature. The structure can be described by two types of polyhedrons, namely disphonoids (TeO 4 E with E = electronic lone pair of Te4+) and octahedrons of ZrO 6. The bridges Te-O 1 -Te and Te-O 2 -Zr ensured the crystal structure cohesion. Both kinds of polyhedron oxygen were coordinated along the [0 1 0] mixed chain, linked to a pure chain of tellurium through O 1 in order to form a two-dimensional network and then a unit cell with a three-dimensional network. The Raman spectrum was dominated by a strong band at 841 cm-1corresponding to Te-O 2 -Zr bridges asymmetric stretching vibration. Consequently, the Te-O 2 and Zr (Mn) O 2 bonds are chemically inequivalent and the Zr O 2 Te bridges are chemically asymmetric. The magnetic results reveal the appearance of a weak ferromagnetic behavior at low temperature.The emission properties of the ZrTe 3 O 8 :2%Er, 3%Mn prepared at relatively high temperature examined at 490 nm excitation led to an appearance of an important emission in the visible and near-infrared domains due to homogeneously occupied Er3+ ions in the host lattice. Therefore, this kind of phosphors may be a meaningful reference for W-LEDs application. [ABSTRACT FROM AUTHOR]
