Abstract

original image

Hierarchical CdS nanotube arrays (see figure) are assembled in an anodic aluminum oxide template from CdS nanoparticles by using a controlled solution precipitation method. The hierarchical nanotube arrays, with high porosity and uniform alignment, display considerably varied photoluminescence and enhanced solid state electro-chemiluminescence in H2O2 solution compared with those of random nanoparticle aggregates.
