摘要

在目前的發展中，奈米科技可說是目前的趨勢，由於奈米科技的發展，人們發現當材料的尺寸縮小至奈米等級時，將會有新的化學及物理性質產生，其中以半導體的量子點與金屬奈米粒子最為熱門，在生醫或光電上領域都有許多新的應用。
　　光電領域中傳統白色發光二極體是利用螢光粉做為波長轉換材料，而量子點具有比螢光粉更好的螢光特性，目前量子點發光二極體也成功的被製做出來，想取代傳統螢光粉，而螢光金奈米團簇相較於量子點為一新型波長轉換材料，且毒性較量子點低，因此本研究開發以螢光金奈米團簇做為波長轉換材料，利用光固化方式，製作具有螢光金奈米團簇的薄膜，以藍光發光二極體激發使其產生白光，並利用固化劑去稀釋金團簇濃度，調整白光發光二極體的光學特性。

Currently, nanotechnology has become the trend in a variety of research fields. Due to development of nanotechnology, it has been found that the material minified into nano-level will lead to new chemical and physical properties, where the semiconductor quantum dots and the metal nanoparticles are popular materials and have been used in a lot of innovative applications in the bio-medicine and photo-electricity.
Traditionally, phosphor is exerted as the wavelength-conversion material for the white light emitting diodes. Quantum dots have superior fluorescent property, therefore, the quantum-dot emitting diodes have been successfully produced for replacing the existing fluorescent-powder emitting diodes. Recently, fluorescence metal nanoclusters are developed to a new type of wavelength-conversion materials which is toxic-free compared to the quantum dots. In this study, fluorescence gold nanoclusters have been used as the wavelength conversion material. The gold nanoclusters were mixed with UV-cured material to fabricate a fluorescence sample. The blue light emitting diodes were used to pump the fluorescence sample and generate white light. The gold nanocluster’s concentration was diluted via the curing agent to adjust the optical properties of white light.
