合成了金量子團簇和納米粒子，研究了它們在飛秒雷射輻照水中的性質。同時所產生的等離子體納米金顆粒也用於染料敏化太陽能電池（DSSCs）的應用。因此，納米金粒子的合成及其量子特性和各自的應用是該研究的主要目標。
在第一項工作中，發現了在水中飛秒雷射脈衝輻照下金量子團簇和納米粒子的量子特性的合成和因素。在實驗中，通過將飛秒雷射照射金離子並且不添加任何還原劑來製備金量子團簇，量子大小的納米粒子。 利用原子力顯微鏡、透射電子顯微鏡、高分辨率透射顯微鏡、紫外 - 可見光譜，螢光分光光度計和一些計算來分析它們產生顆粒的量子特性。通過照射時間和飛秒脈衝雷射強度的影響，可以研究量子團簇和納米粒子的尺寸和量子特性。該方法將提高對金原子團簇（量子團簇）的量子特性的理解，特別是那些反映從孤立原子到納米粒子的過渡理論，並且比起化學和/或物理還原方法更具有簡單、純度和尺寸可控性方面的優勢。 在第二項工作中，氧化鋅納米線（ZnONW）在奈米纖維纖維素存在下通過原位方法生長，以製造有彈性和導電複合膜。該導電複合膜用作基底以沉積氧化鋅納米顆粒，碳點和染料敏化太陽能電池的金納米顆粒工作電極的複合物，其中在飛秒激光照射下產生等離子體金納米顆粒。優化的光陽極提供了導電聚合物柔性薄膜對電極的效率。該效率低於由在固體導電基底上具有氧化鋅納米顆粒的複合工作電極等離子體金納米顆粒和Pt對電極組成。

Gold quantum clusters and nanoparticles were synthesized and studied their property under femtosecond laser irradiation in water. Additionally, the produced plasmonic gold nanoparticles were also used for dye-sensitized solar cell (DSSC) application. Hence, synthesis, quantum property and respective applications of the gold nanoparticles are the major objectives of the study.
In the first work, the synthesis and factors that govern their quantum properties of gold quantum clusters and nanoparticles under femtosecond laser pulses irradiation in water were studied. In the experiments, gold quantum clusters, and nanoparticles were produced by irradiating femtosecond laser to the gold ions without adding any reducing agent. Atomic force microscopy, transmission electron microscope, high resolution-transmission microscope, UV-Visible spectroscopy and some calculations were applied to analyze their quantum property of the produced particles. The size and properties of quantum clusters and nanoparticles can be studied through the influence of irradiation time and intensity of femtosecond pulse laser. The strategy leads to improve the understanding about quantum properties of gold atomic clusters (quantum clusters). The results particularly reflected the transition from isolated atoms to nanoparticles and demonstrated advantages of physical reduction method compared to chemical methods with regard to technical simplicity, product purity and size controllability.
In the second work, zinc oxide (ZnO) nanowires were grew by in situ method on flexible substrate This conductive composite film was used as a substrate to deposit composites of ZnO nanoparticles, carbon dots and gold nanoparticles working electrodes of the dye-sensitized solar cells (DSSCs), where plasmonic gold nanoparticles were produced under femtosecond laser irradiation. The optimized photoanodes provided the efficiency of conductive polymer flexible film counter electrode. This efficiency was lower than that of DSSC consisting of a composite working electrode plasmonic gold nanoparticles with ZnO nanoparticles on solid conductive substrate and a Pt counter electrode.
