Abstract: (1514 Views)
In this research, colloidal Cadmium Sulfide (CdS) quantum dots were synthesized via an aqueous solution synthesis method. In order to investigate the linear and nonlinear optical properties of these quantum dots, photoluminescence (PL) spectrum, absorption spectrum and close aperture diagram of the Z-scan technique were measured and studied. Results showed that these QDs can be a great candidate to be used in a variety of optoelectronic devices such as QLEDs and Optical limiting devices due to their bandgap of 2.81 eV, emission peak around 548 nm and nonlinear refractive coefficient of -1.98×10-10 cm2/W.
