SUMMARY OR ABSTRACT
Text of Note
Semiconductor nanocrystals have great interest due to their unique optical properties such as the particle size and the alloy composition dependent spectra, photochemical and colloidal stability. They have wide range of potential applications like solar cells, light emitting diodes (LED) and bioimaging etc. In this thesis, colloidal ternary Cu doped and undoped ZnSxSe1-x nanoalloys were synthesized by modified one pot aqueous approach. TGA and MPA ligands were used as capping agents for the synthesis of ZnSxSe1-x and Cu doped ZnSxSe1-x colloidal nanoalloys. The results showed that capping agents have an significant effect on optical properties of ZnSxSe1-x nanoalloys. Although the TGA capped nanoalloys have well-defined absorption bands rather than MPA capped ones, ZnSxSe1-x nanoalloys with TGA capping agent fluorescence peak was not observed. Therefore, the further study was continued with MPA capped ZnS xSe1-x ternary nanoalloys. Optical spectra demonstrated both absorption and PL spectra were shifted due to the adding of Cu dopant. Absorption peak shifted from 335 nm to 376 nm. Fluoroscence spectra also was redshift from 469 nm to 565 nm. Thus, we can conclude that, colloidal ternary nanoalloys optical properties can be tuned by using chemical doping. On the other hand, the optical and structural properties of binary ZnSe QDs, Mn and Cu doped ZnSe nanocrystals were investigated. We concluded that ZnSe and ZnS xSe1-x nanocrystals can be used to synthesize doped nanocrystals by chemical doping. We demonstrated that optical and structural properties of Cu and Mn doped ZnSe can be tuned by chemical doping.
