My name is Liu Wei Ting, and I hold a Master’s degree in applied chemistry which was awarded to me by National Chiao Tung University (NCTU). My Master’s thesis was to synthesize novel solid-state phosphors. 1. Do Rietveld refinement on x-ray diffraction patterns by TOPAS. 2. Analyze the structure of crystalline materials by x-ray diffraction in National Synchrotron Radiation Research Center (NSRRC). 3. Analyze phosphors of wavelength, wavelength of full width at half maximum (FWHM) and decay times by fluorescence spectroscopy analyzer. 4. Analyze phosphors of absolute quantum yields by Integrating sphere. 5. Analyze phosphors of thermal stability. After graduating from NCTU, I have been working as a product development engineer for Epistar Corporation. 1. Familiar with production process of elastomer stamp mass-transfer of mini/micro light-emitting diode. 2. Assisted and advised engineering department with improving their product development process. 3. Estimated the possibility of new processes.
