“…As a well-known inorganic functional material, rare earth compounds, such as hydroxides [3][4][5], oxides [6][7][8], phosphates [9,10], vanadates [11,12], borates [13,14], fluorides and sulfides [15][16][17], have been extensively studied because of their large potential applications in high-performance luminescent and magnetoresistance devices, catalysts and electrodes because of their outstanding optical, electrical and magnetic properties arising from their unique electronic structures, which involve 4f electrons. However, dimensionality and morphology are now considered to be the particularly important factors that could influence the chemical and physical properties of the synthesized materials.…”
