摘      要：宽范围精准调控非晶材料的光学性能是面向光电器件等潜在应用亟需解决的关键问题之一.研究发现,通过在非晶合金CoFe-Ta-B体系中引入氧可以诱导金属-绝缘体转变,从而制备出一系列涵盖金属、半导体和绝缘体的非晶态衍生物.随着氧含量的不断增加,这些含氧非晶态衍生物的光学带隙打开,薄膜逐渐变得透明.复合高反射率的非晶合金和高透过率的非晶氧化物形成的双层薄膜结构可以实现可见光波段的全色谱可调.该研究结果为研制具有高硬度、高耐磨性、设计制备简便、全色谱可调等优异性能的大面积彩色涂层提供了一条新的途径.同时,该研究提出的设计理念可能适用于已报道的很多非晶合金体系,通过这种氧调控方式可制备出涵盖金属、半导体和绝缘体所有导电类型的非晶材料,用于研制基于这些材料光学功能特性的器件.
