ZnO is a wide bandgap (3.4 eV) semiconductor which is transparent in the visible range. Wurtzite ZnO has the fastest growth rate along its (0 0 0 1) face which makes it easy to grow into one-dimensional (1D) nanocrystals. The 1D geometry, coupled with the dislocation-free single-crystalline nature, high index of refraction and atomically smooth surfaces, allow for sufficient end-facet reflectivity and photon confinement in a volume of just a few cubic wavelengths of the material.
