© 2015 Elsevier Ltd.Abstract Nd3+-doped YVO4 nanophophors were prepared using modified Pechini method. Synthesized samples consist of large particles about 1 micron and weakly agglomerated nanoparticles with size about 200 nm. The effect of the doping concentration on the structure and luminescence was investigated. It was found that increase of Nd3+ concentration leads to the growth of unit cell parameters and red shift of Raman lines. Concentration dependence on the luminescence intensity was studied under different excitation wavelengths. Decay curves of 4F3/2-4I11/2 transition were observed for different doping concentration. Lifetime of excited level 4F3/2 was obtained from fitting.
