| Abstract: | In order to study the assembly methods of various micro-nanometer materials and micro-structures, the fabrication of micro-structures and the working mode of micro-assembly systems are first studied. The femtosecond laser two-photon polymerization micro-machining technology is employed to fabricate a fine three-dimensional “arch” micro-structure with a base, with 250μm in height, 300μm in length and 50μm in thickness. The micro-structure is combined with the two-dimensional micro-assembly platform independently built in the laboratory, and the self-designed human-computer interface is used to drive the stepping motor. The micro-assembly device can be remotely controlled to assemble the fluorescent scintillation ceramic powder (hereinafter referred to as fluorescent powder) into the micro-structure. Through the fluorescence spectrum characterization of the assembled micro-structure, the results show that the emission spectrum of the pure fluorescent powder and the fluorescent powder in the micro-structure is basically the same within the measurement error range, and the optical properties of the fluorescent powder remain unchanged. Through this experimental device, we can implement the electric assembly of fluorescent powder and micro-structure without affecting the properties of fluorescent powder. We can also use this device to assemble a vast variety of micro-nanometer materials and micro-structure so as to form the micro-structure system with different materials. |
