Electroluminescence Property of Si-Nanocrystallites-Embedded-in-SiO2-Matrix Framework Prepared by Electrochemically Etching
电化学腐蚀法制备的SiO2包裹纳米硅颗粒结构的电致发光特性

The Si nanocrystallites embedded in SiO 2 matrix framework is formed in the surface of the traditional electrochemically produced samples after being peeled off the surface porous film in the marinade.A semitransparent gold film is evaporated on the surface of the sample to form EL device.A stable green EL can be obtained from the samples,and it gets stronger along with the applied voltage,but the EL peak position does not change.The EL mechanism is discussed.
