在难熔金属表面大面积制备周期性微结构是支持表面微腔光谱控制热辐射实际应用的关键技术。本文描述了在镍基高温合金上利用自组织技术大面积制备二维亚微米准周期微腔。通过热处理和简单的化学蚀刻，获得了大块金属表面的微腔。通过控制微腔尺寸从0.27 μ m到0.53 μ m，可以调节腔内受限模式的发射峰，并在973 K时证实了发射度增强和热稳定性。(C) 2012年美国物理研究所。[http://dx.doi.org/10.1063/1.4767903]
Large-area fabrication of periodic microstructures on refractory metals surface is a key technology supporting the practical application of spectrally controlled thermal radiation using surface microcavities. This report describes large-area fabrication of two-dimensional submicron quasi-periodic microcavities using self-organization on a nickel-based superalloy. The surface microcavities on a bulk metal are obtained by heat treatment and simple chemical etching. The emission peak attributed to the confined modes inside cavities can be tuned by controlling the microcavity size from 0.27 to 0.53 mu m. Emittance enhancement and thermal stability are also confirmed at 973 K. (C) 2012 American Institute of Physics. [http://dx.doi.org/10.1063/1.4767903]
