Hydrothermal Route

Twin crystalline ZnO nanorods with tunable amorphous joints are synthesized via a hydrothermal route. We find a strong coupling of acoustic phonon modes to free excitons in these structures. As a result, significant non-radiative transfer of carriers from the conduction band to defect bands occurs, leading to a loss of the near band edge emission intensity below ∼180 K.
