White light luminescence and room‐temperature lasing throughout the visible are demonstrated for ZnO nanocolumns grown on Au‐coated tin‐oxide glass. The directionality of the emission, the lasing threshold, and the observed mode spacing are all consistent with Fabry–Pérot lasing cavities. The Figure shows a cross‐sectional SEM image of ZnO nanocolumns with an average nanocolumn length of ∼ 3 μm.
