The one-dimensional (1D) crystalline nanostructures of Y(OH)₃:Eu/Tb have been synthesized using softemplate method at temperature range of 180 – 200 °C for 24 h. The studies by Field Emission Scanning Electron Microscopy (FESEM) have been determined that the outer and interior hollow diameter of Y(OH)₃:Eu/Tb nanotubes was obtained range from 150 to 500 nm and 100 to 300 nm, respectively and of the length up to several micrometers, respectively. The Y₂O₃:Eu/Tb nanorod/tubes have been obtained from Y(OH)₃:Eu/Tb counterparts by crucial annealing. The Xray diffraction (XRD) patterns indicated that the Y(OH)₃:Eu/Tb and Y₂O₃:Eu/Tb nanorods and nanotubes obtained has hexagonal and cubic phase with high crystaline. The luminescence and excitation properties of Y(OH)₃:Eu/Tb and Y₂O₃:Eu/Tb nanorods and nanotubes were investigated in details. It found that crystal form and nanomorphology of Y(OH)₃ and Y₂O₃ have played a great role on the emission properties of the doped Eu³⁺ ions.
