Development of organic optical amplifier by cladding excitation

我已经开发了一种由连续波光驱动的可见光放大器。这项研究的主要问题是合适的材料：使用的激光染料不具有耐热性。因此，我采用了噻吩苯/苯撑共低聚物(TPCO)，它们在结晶状态下显示出良好的发射能力，并被用于可变研究。建立在不同衬底上生长晶体的方法很重要。研究了TPCO晶体生长的两种方法：气相生长和液相生长。在气相法的情况下，使用气相沉积，然后进行热处理。液相法是将TPCO溶液滴入劣质溶剂的液滴中，形成亚毫米尺寸的TPCO单晶。

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.
