碩士 === 國立臺南大學 === 材料科學系碩士班 === 107 === The unique perovskite (CsPbBr3) crystal structure makes it have various physicochemical properties, such as light absorbance and electro-catalysis. It has a wide range of applications in the fields of chemistry and physics, and the process of making CsPbBr3 is easy. In this study, the self-assembly mechanism of nanogold particles, combined with electron beam lithography, DNA functional group modification and electrostatic charge adsorption, were used to create gold particle patterns at specific locations, and perovskite (CsPbBr3) and paired DNA were used. After mixing, it is adsorbed on the nanogold particles. Through this technology, perovskite particles can be arranged in a variety of different patterns at specific locations, making the application more widely available.
