SiO₂: Sm³⁺ nanotube arrays with excellent antireflective property at 1.06 μm were synthesized by a template-assisted sol–gel process. The molecular structure, morphology and optical properties of the fabricated SiO₂:Sm³⁺ nanotube arrays were investigated by a Fourier transform infrared spectroscope (FTIR), a Scanning electron microscope (SEM), and a spectro-fluorometer, respectively. The experimental results demonstrate that the SiO₂:Sm³⁺ nanotube arrays were formed via the AAO membrane during the sol–gel process. The remarkable antireflective characteristic of about 0.166% at 1.06 μm was attributed to the drastic decrease of effective refraction index which enhances the matching effect between air and substrate. As well as the absorption performance of Sm³⁺ at 1.06 μm which consumes the energies of incident light. - Graphical abstract: Directional aligned SiO₂:Sm³⁺ nanotube arrays were synthesized in AAO template by sol–gel process, and the antiflective performance of arrays is prominent comparing to the blank AAO template. Highlights: • SiO₂:Sm³⁺ nanotube arrays are synthesized by a template-assisted sol–gel process. • SiO₂:Sm³⁺ nanotube arrays have remarkable antireflective properties at 1.06 μm. • The subwavelength structure results in a decrease of effective refraction index. • The absorption performance of Sm³⁺ at 1.06 μm consume the energies of incident light.
