They're thin, really thin… Aligned ultrathin (3–10 nm) ZnO nanofibers with a length of ≈500 nm in a dense array were synthesized from and on a Zn substrate by hydrothermal treatment of Zn foil in an aqueous ammonia/alcohol solution (see SEM image). The near‐band‐edge emission is significantly blue‐shifted to 373 nm (3.32 eV), thus clearly suggesting quantum confinement effects for these ultrafine nanofibers.
