a FT patterns of the randomly assembled ZnS nanosheets with different pumping intensity. The arrow indicates the cavity length, L, of the fundamental closed-loop cavity modes. b A schematic diagram shows the formation of closed-loop path of light obtained from recurrent light scattering under different excitation intensity
