摘要
硅纳米晶粒具有独特的光致发光(PL)和电致发光(EL)特性,在纳米光电子器件中具有巨大的潜在应用价值。通过近年来硅纳米晶粒的研究成果,总结了影响硅纳米晶粒发光特性的各种因素和各种条件下的发光机制,并综合评述了硅纳米晶粒在发光二极管、激光器等纳米发光器件及荧光粉等方面的应用,指出了未来硅纳米晶粒的研究方向。
Silicon nanocrystals have special photoluminescent (PL)and electroluminescent (EL) characteristics, so they will have huge potential application value in photoelctronic nanodevices. Based on the research results of silicon nanocrystal in recent years,series of factors that influence the luminescence properties of silicon nanocrystals and the luminescence mechanism of silicon nancrystals in different conditions are summarized in this paper. Moreover, we comprehensively discuss the application of silicon nanocrystals in light emitting devices such as light emitting diode, laser etc and in fabrication of nanophosper,and then we point out the development direction of the research of silicon nanocrystal in future.
