Among the various approaches to synthesizing fluorescent nanocrystals that do not contain high performance heavy metals to replace the Quantum dot, representative ZAIS has superior properties including longer fluorescence lifetime and higher brightness than QD without photoblinking. We applies 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. We investigated the regulatory factors of ultrasonic chemical parameters such as ultrasonic power, temperature and reaction time for high performance ZAIS synthesis and found optimal reaction conditions. The interaction between the ligand and surface of ZAIS should be understood as one of the important factors of ZAIS synthesis. We have investigated the effects of various polymer-based ligand and optimal reaction condition for ZAIS synthesis. |
