本文介绍了在稀土离子Re(Re=Er、Eu、Tb、Ce和Gd)注入的SiO2金属-氧化物-硅(MOS)结构高效率电致发光器件的研究进展情况.通过将不同的稀土离子注入到SiO2薄膜,相继获得了发射光谱峰值分别位于红外(1.54μm)、可见光(618 nm、543 nm、440 nm)至紫外(316 nm)光谱范围的MOS结构电致发光器件,并系统研究了SiO2:Re薄膜中稀土离子的电致发光特性.在SiO2:Re有效发光层的厚度为50 nm,掺杂浓度为1-3%的条件下,稀土Er、Tb和Gd离子注入掺杂的硅材料MOS结构电致发光器件在红外、绿光和紫外的量子效率分别达到14%、16%和5%,接近了商品化Ⅲ-V族半导体发光二极管的水平.
