摘要：

A novel one-dimensional (ID) hollow nanostructure of SrS:Eu2+, Dy3+ with red long lasting phosphorescence was successfully fabricated by a soft template method followed by annealing treatment at 900 degrees C. The ID nanostructures are 60-100nm 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. (c) 2007 Elsevier B.V. All rights reserved.
