제목 Optmization of sonochemical and ligand parameters for high photophysical performances of (ZnxAgyInz)S2 nanoparticles
초록 Various solid solution-based fluorescence nanoparticles such as CuInS2, AgInS2 and ZnS-AgInS2 (ZAIS) have drawn the attention because of its heavy metal-free nature, longer fluorescence lifetime, higher brightness, and emission wavelength tuning by the composition ratios. Herein, we designed (ZnxAgyInz)S2 (ZAIS) nanoparticle library by fixing Zn component at a ratio of 0.1 and varying the In as well as Ag rations, in order to search the optimal quantum yields, emission wavelength, and their intensities according to the Zn, In and Ag ratios. As a result, we could specify and find out the specific composition ratios of Ag, In, and Zn which are optimal for the fluorescence properties of a specific emission wavelength. We tried to see the wavelength and intensity according to the ratio of Ag: In: Zn, but we could not see the tendency of the ratio. We found the best wavelength and intensity at various ratios from 580 nm to 620 nm at 10 nm intervals.
