    We investigate the case that the transport mean free path of emitted photons within the disordered scatterers, which is composed by the ZnO nanowires, is tunable by a curvature bending applied on the flexible substrate underneath, thereby creating a unique light source which is able to be operated above and below the lasing threshold for desirable spectral emissions..
