•We demonstrate that multi-wavelength emission can be achieved within individual microrods.•The excitonic properties of GaZnO microrods are mediated by local Ga concentration.•Self-induced defect engineering is revealed by DFT calculations.•The geometry of ZnO microrods can be altered by Ga additive...
