The gadolinium vanadate doped with samarium (GdVO4 :Sm3+) nanopowder was prepared by the solution combustion synthesis (SCS) method. After synthesis, in order to achieve the full crystallinity, the material was annealed in air atmosphere at 1300 °C. Phase identification in the post-annealed powder samples were performed by X-ray diffraction, and morphology was investigated by high resolution scanning electron microscope (SEM). Photoluminescence characterization including excitation and emission spectra and lifetime analysis has been done using tunable laser optical parametric oscillator excitation and streak camera. Several strong emission bands in Sm3+ emission spectrum were observed, located at 563 nm (4 G5/2 – 6 H5/2), 600 nm (4 G5/2 – 6 H7/2,), and 644 (653) nm (4 G5/2 – 6 H9/2,), respectively. The weak emission at 700-710 nm (4 G5/2 – 6 H11/2) was also observed by detection system.
