Abstract

Green phosphors of Y_2-x(MoO₄)₃:Er³⁺/Yb³⁺ with doping concentrations of Er³⁺ and Yb³⁺ (x = Er³⁺ + Yb³⁺, Er³⁺ = 0.05, 0.1, 0.2 and Yb³⁺ = 0.2, 0.45) were synthesized via the cyclic microwave-assisted sol-gel route and their upconversion properties were investigated. Well-crystallized particles, formed after heat-treatment at 900 °C for 16 h, showed a fine and homogeneous morphology with particle sizes of 5-10 μm. Under excitation at 980 nm, Y₂(MoO₄)₃:Er³⁺/Yb³⁺ particles exhibited a strong 525 nm and a weak 550 nm emission bands in the green region and a very weak 655 nm emission band in the red region. Raman spectra of the particles indicated the presence of strong peaks at both higher frequencies and lower frequencies induced by the disorder of the [MoO₄]^2- groups with the incorporation of the Er³⁺ and Yb³⁺ elements into the crystal lattice or by a new phase formation.
