We report on the growth of Nd_2-xCe_xCuO_4-δ single crystals (0<x<0.2) from Cu₂O flux. Free separated crystals with maximum size of 5x8x0.15 nm³ have been obtained. Magnetic AC susceptibility measurements show a sharp superconducting transition at temperatures up to 23 K. The temperature dependence of the lattice parameters has been measured by means of X-ray powder diffraction between 10 K (α=3.9413(3) Å, c= 12.0290(18) Å) and 290 K (α=3.9482(3) Å, c= 12.0590( 18) Å). Room temperature Raman spectra reveal a new band at 320 cm^-1 which is not observed in Nd₂CuO₄. Raman spectra of crystals with T_c ranging from 7 to 22 K show a systematic intensity change of the broad band at 590 cm^-1.
