摘　　要：表面等离子体共振被广泛应用于光催化、纳米集成光子学、光学传感、生物标记、医学成像、太阳能电池以及表面增强Raman光谱等方面。除了金属纳米材料以外,一些非金属纳米材料也具有表面等离子体共振特性,如自掺杂半导体、外掺杂半导体、导电过渡金属化合物等。非金属等离子体共振纳米材料具有来源丰富、制备方便、价格合适、熔点高、耐磨、化学稳定性好、表面等离子体共振特性可调等优点,受到越来越多的关注。本文系统地梳理了文献中关于非金属等离子体共振纳米材料的研究,将其归类为p型半导体、n型半导体和金属型过渡金属化合物,评述了各自的特点及研究进展,并与金属纳米材料的表面等离子体共振效应进行了比较,提出了需注意的研究问题及进一步的研究方向。Surface plasmon resonance（SPR） is widely applied in a number of realms such as photocatalysis, integrated nanophotonics, optical sensing, bio-labeling, medical imaging, solar cell and surface-enhanced Raman spectroscopy. Besides metallic nanomaterials, some nonmetallic nanomaterials also possess surface plasmon resonance properties including self-doped semiconductors, extrinsically-doped semiconductors, conductive transition metal oxides and metal nitrides. Nonmetallic SPR nanomaterials have attracted much attention due to their rich resources, convenient preparation, appropriate price, high melting point, good abrasion resistance and chemical stability, and adjustable SPR properties. In this paper, nonmetallic materials were classified as p-type semiconductors, n-type semiconductors and metal-type transition metal compounds, and their characteristics and research progress were discussed via systematically summarizing research work on nonmetallic SPR nanomaterials in the literatures. The main differences and similarities of SPR properties between nonmetallic and metallic nanomaterials were also compared. In addition, we analyzed the existing problems and gave the further research directions.
