7月30日上午，白俄羅斯科學(xué)院物理研究所院士Sergey Gaponenko教授和Olga Kulakovich研究員在5號教學(xué)樓502-1會議室為北理工材料學(xué)院師生分別作題為“Principles of Nanophotonics”“Polarized photoluminescence from CdSe nanoplatelets and quantum dots in stretched PVA films”的學(xué)術(shù)報告,。該報告會系我院“21世紀(jì)學(xué)科前沿”系列學(xué)術(shù)交流活動之一,。會議由材料學(xué)院李紅博教授主持,，材料學(xué)院30余名師生聆聽此次報告。
十年前,，納米光學(xué)被認(rèn)為是一個新興的科學(xué)領(lǐng)域,，如今它正成為現(xiàn)代光電技術(shù)的活躍領(lǐng)域，包括顯示設(shè)備,、光源,、激光和光通信元件。Sergey Gaponenko院士詳細(xì)講述了其主要的物理現(xiàn)象,，即納米光學(xué)的基礎(chǔ),，并結(jié)合實例生動地分析它們在現(xiàn)有和新興的光電器件中的應(yīng)用。在許多發(fā)光結(jié)構(gòu)的應(yīng)用中,，線性極化輻射是必要的,，這很容易用激光來實現(xiàn)，但對于發(fā)光的光源,，如LED或光轉(zhuǎn)換熒光粉卻很難做到,。線性偏振背光輻射是LCD的器件的必要條件，在現(xiàn)代LCD屏幕中設(shè)計線性偏振背光源,，效率可能會更高,。Olga Kulakovich研究員介紹了嵌入各向異性膠態(tài)發(fā)光物的拉伸聚合物薄膜，這是在非極化光激發(fā)條件下獲得極化光致發(fā)光的合理方法,。Olga Kulakovich研究員生動詳細(xì)地介紹了利用金納米棒在拉伸PVA薄膜中用CdSe納米片和量子點進行偏振光致發(fā)光的研究結(jié)果,。本次報告會氣氛熱烈,，開拓了師生們的視野，會后師生與Sergey Gaponenko教授和Olga Kulakovich研究員開展了深入細(xì)致的討論,。
