STUDYING ZINC OXIDE/COPPER OXIDE/CADMIUM SELENIDE NANOSTRUCTURES FOR LIGHT EMITTING DIODES

The synthesis of zinc oxide, copper oxide, and cadmium selenide as a heterostructure was conducted using a simple co-precipitation method. Structural, optical, and electrical properties were investigated. XRD patterns  show hexagonal form for ZnO, cubic for CuO, and wurtzite for CdSe, with an average particle size of 18.5,  22.3, and 38.2 nm for ZnO, CuO, and CdSe, respectively. SEM images show ZnO crystals with a nanorod shape and CuO and CdSe nanoparticles with nano-branch agglomerations in all directions. Optical properties exhibit a redshift in absorbance (460 nm) with photoluminescence peaks at 500 nm for the heterostructure and a broadened band gap (2.5 eV). In light, the heterostructure shows increased light absorption, leading to enhanced electron-hole production and an exponential increase in forward current. These results enhance the success of fabrication of high-amplification light-emitting diodes.
