Abstract: Uniform AgLnMo₂O₈(Ln=La, Nd, Eu) hierarchical architectures were firstly synthesized via a facile hydrothermal method. These three dimensional architectures were assembled from primary micro-rods and the average diameter was about 5 mm. According to the time-depend experiments, a possible growth mechanism was proposed to be a self-assembling process followed by an Ostwald ripening step. The concentrations of precursor and pH value were also found to have great influences on the final morphologies of the products. In addition, the photoluminescence properties of the products were investigated.
