abstract = "© 2018 Elsevier B.V. In recent years, there exists a tendency in research of up-conversion materials to shift excitation from 980 nm to shorter wavelengths. Here, in order to produce up-conversion luminescence emission of GdVO4-based materials under 808 nm excitation, polycrystalline powders of GdVO4:Er3+/Nd3+and GdVO4:Ho3+/Nd3+were successfully prepared by a high-temperature solid-state reaction technique. The prepared powders were highly crystalline with a single-phase zircon-type GdVO4structure and consisted of micrometer-sized irregular spherical particles (2–6 μm in diameter). In all studied samples, visible up-conversion luminescence was successfully achieved under 808 nm illumination. Near-infrared pumping produced emission bands in the green, yellow-orange and green regions of the visible spectrum. The bands in the green and red regions of GdVO4: Er3+/Nd3+as well as GdVO4:Ho3+/Nd3+were, respectively, characteristic of Er3+and Ho3+ions. The dominant band originating from the4G7/2→4I11/2transition in Nd3+ions was observed around 597 nm in all samples.",
