Although quantum dot has received attention due to its excellent and unique fluorescence properties such as brightness, photostability, size dependence in emission wavelength, its toxic heavy metals limit biological applications. ZAIS has excellent properties including long fluorescence lifetime and higher brightness than QDs without photoblinking. Here, we applied the sonochemical approach to the synthesis of (ZnxAgyInz)S2 (ZAIS) NC, which is simple, rapid, and efficient to create a library of ZAIS containing the information of fluorescence colors and intensities according to ratios of each component – Zn, Ag, In. In addition, the interaction between the ligand and surface of ZAIS should be understood as one of the important factors of ZAIS synthesis. Therefore, we have investigated the effects of various polymer-based ligand and optimal reaction condition for ZAIS synthesis. |
