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 F-4(3/2)-I-4(11/2) transition were observed for different doping concentration. Lifetime of excited level F-4(3/2) was obtained from fitting. (C) 2015 Elsevier Ltd.
