Abstract :
Hybrid inorganic/organic Cd-doped ZnO nanostructures called CZO nanohybrids were electrochemically synthesized on Ga-doped ZnO/Si. The CZO nanohybrids comprise alternating layers of organic surfactant and CZO inorganic phase. These lamellar structured nanohybrids were found to be c-axis oriented, perpendicular to the substrate with good crystallinity. During photoluminescence measurement, a strong orange emission from CZO was observed. The nanohybrids were found to have band gap of 3.3 eV, indicating band gap shrinkage relative to ZnO. The nanohybrids hold great promise for the development of hybrid inorganic/organic light-emitting devices.
