7月30日上午，白俄罗斯科学院物理研究所院士Sergey Gaponenko教授和Olga Kulakovich研究员在5号教学楼502-1会议室为北理工材料学院师生分别作题为“Principles of Nanophotonics”“Polarized photoluminescence from CdSe nanoplatelets and quantum dots in stretched PVA films”的学术报告。该报告会系我院“21世纪学科前沿”系列学术交流活动之一。会议由材料学院李红博教授主持，材料学院30余名师生聆听此次报告。

　　十年前，纳米光学被认为是一个新兴的科学领域，如今它正成为现代光电技术的活跃领域，包括显示设备、光源、激光和光通信元件。Sergey Gaponenko院士详细讲述了其主要的物理现象，即纳米光学的基础，并结合实例生动地分析它们在现有和新兴的光电器件中的应用。在许多发光结构的应用中，线性极化辐射是必要的，这很容易用激光来实现，但对于发光的光源，如LED或光转换荧光粉却很难做到。线性偏振背光辐射是LCD的器件的必要条件，在现代LCD屏幕中设计线性偏振背光源，效率可能会更高。Olga Kulakovich研究员介绍了嵌入各向异性胶态发光物的拉伸聚合物薄膜，这是在非极化光激发条件下获得极化光致发光的合理方法。Olga Kulakovich研究员生动详细地介绍了利用金纳米棒在拉伸PVA薄膜中用CdSe纳米片和量子点进行偏振光致发光的研究结果。本次报告会气氛热烈，开拓了师生们的视野，会后师生与Sergey Gaponenko教授和Olga Kulakovich研究员开展了深入细致的讨论。
