Photothermal therapy (PTT) has been widely applied in cancer therapy as a result of its non-invasive, localized treatment and good therapeutic effect. In general, the final therapeutic effect of PTT mainly depends on the photothermal materials, which can be further considered to be determined by the photothermal conversion efficiency, biocompatibility, and photothermal stability of photothermal materials. In this review, photothermal materials including inorganic materials, organic materials, and organic–inorganic composite materials in recent years have been summarized in terms of the mechanism, preparation, and cancer therapy applications. In the end, the perspectives and obstacles in their further development are overviewed.

近红外光热转换材料：机理、制备和光热癌症治疗应用

光热疗法（PTT）由于其无创、局部治疗和良好的治疗效果，在癌症治疗中得到了广泛的应用。一般来说，PTT最终的治疗效果主要取决于光热材料，进一步认为是由光热材料的光热转换效率、生物相容性和光热稳定性决定的。本文就近年来光热材料包括无机材料、有机材料和有机-无机复合材料等从机理、制备和癌症治疗应用等方面进行综述。最后，概述了它们进一步发展的前景和障碍。
