Abstract-The ZnS:Cu Quantum dots were synthesized specially for green emission light in the QD-OLED. XRD, UV-Vis and PL analysis were done to investigate of the optical and structural properties. It is found that, the synthesized nanoparticles were single phase and have the cubic structure with average size about 3.9 nm. Spectrum of photoluminescence ZnS:Cu with various amounts of doping Cu were investigated, while whit excitation wavelength of 325 nm was gotten emission wavelength in the range of 500 to 520 nm. In this work we get the final intensity emission with 0.2 percent doping impurity. I-V characteristic curve of the QD-OLED diode was showed and investigating it's properties.
Keywords: Semiconductor, Diode, ZnS:Cu, QD-OLED, PEDOT:PSS.
