Abstract
A novel one-dimensional (1D) hollow nanostructure of SrS:Eu 2+, Dy 3+ with red long lasting phosphorescence was successfully fabricated by a soft template method followed by annealing treatment at 900 °C. The 1D nanostructures are 60–100 nm in diameter and several hundreds nanometers in length. The TEM image indicates that the 1D nanostructure could be considered to be assembled in lines by lots of nano-hollow spheres. The properties of photoluminescence and afterglow of the 1D nanostructure were also investigated and discussed.
