Green Photoluminescence In Tb3+-Doped Zro2 Nanotube Arrays

Abstract

Tb3+-doped ZrO2 nanotube arrays were fabricated by anodizing Zr–Tb (3 at.% Tb) alloy, which was prepared through a powder metallurgical method. The effects of electrolyte and annealing temperature on the morphologies, structures, photoluminescence properties and decay times of the nanotube arrays were studied. The nanotubes prepared from aqueous electrolyte is of tetragonal ZrO2, while the nanotubes prepared from organic electrolyte (formamide and glycerol) is of amorphous structure that can be converted to monoclinic ZrO2 after annealing at 600 °C. Under an excitation wavelength of 263 nm, the nanotubes annealed at 400 °C display a strong photoluminescence emission at 544 nm which is associated with 5D4–7F5 transitions of Tb3+. The tetragonal ZrO2 in the nanotubes was revealed to be beneficial for the improvement of the luminous efficiency and decay time.
