摘要:
通过热注射法制备高质量的CdSe/ZnS绿色量子点,采用不同配方的醇和烷烃作为洗涤溶剂通过沉淀法纯化量子点粗产品,并制备基于液晶显示器的量子点光学转换膜。通过色彩分析仪检测分析,研究在高温、高湿、蓝光照射条件下量子点膜的光学稳定性。采用核磁共振氢谱等方法和技术对纯化后量子点的表面配体进行分析。实验结果表明,不同的纯化试剂改变了量子点表面油酸及三辛基氧膦配体数量,从而影响了量子点膜的光学稳定性。
Abstract:
Highly luminescent CdSe/ZnS quantum dots were synthesized by hot injection method and further purified with the different alkanes and alcohols to prepare the quantum dot optical conversion films used in liquid crystal display. The optical stability of the quantum dots film under the conditions of high temperature,high humidity and blue light irradiation was investigated by color analyzer. The surface ligands of quantum dots were also characterized by nuclear magnetic resonance spectroscopy. The experimental results show that the number of oleic acid and trioctyl oxyphosphine ligands on the surface of quantum dots changes with the different purified reagents,influencing the optical stability of the quatum dot films.
