| Research Abstract |
I have developed a visible region amplifier driven by CW light. The main issues in this study were suitable materials: the used laser dye did not have a thermal tolerance. Therefore, I employed thiophene/phenylene co-oligomers (TPCOs), which show excellent emission ability in their crystalline state and are utilized in variable studies. It is important to establish methods of crystal growth in varied substrates. I have researched two types of crystal growth methods of TPCOs: through vapor phase and liquid phase. In the case of vapor phase method, vapor deposition was used, followed by thermal treatment. The liquid phase method was the dropping of TPCO solution into the droplet of poor solvent, causing in sub-millimeter-sized single crystals of TPCOs.
