项目摘要

Thermal radiation is an electromagnetic wave originated from thermal vibration of charged particles in a material. It is industrially or naturally easily obtainable energy. However, it is dispersed over a wide spectral region covering the Planckian distribution on its own, and it is also weak directional indistinct radiation. Therefore, it is not often effective to concentrate its energy on a specified wavelength (band or region) and bring out engineering functions as in the case of laser beam.The present study aims to develop new techniques for controlling and converting the thermal radiation into spectral functional radiation which emphasizes an specified wavelength band. In the present study, on the basis of electromagnetic wave theory, spectroscopy, solid state physics and heat transfer science and engineering, we make experimental and theoretical studies of spectroscopic thermal engineering in order to realize hardware systems which is effective for energy engineering and life env … More ironmental engineering.Specifically, in the term of the three years (2005-2007), Makino, Wakabayashi and Matsumoto (Kyoto University) considered (1) interference of spherical wave of thermal radiation emitted by a film system and (2) a theoretical model in which an electromagnetic wave theory for a spherical wave is combined with Planck's theory of thermal radiation, and (3) fabricated film system type emitters. (4) They developed a new excellent wide-spectral-range high-speed spectrophotometer system for simultaneous measurement of spectra of specular reflectance, hemispherical reflectance and directional emittance of surfaces, and (5) they experimentally verified Kirchhoffs law on thermal radiation at an electromagnetic wave level. In addition, Makino actively made several plenary, keynote and review speeches in several domestic symposiums and international conferences on thermal engineering from the viewpoint of his supervisor position of the present study. Yoshida (Kyoto University) thermal-systematically considered thermovoltaic and thermophotovoltaic generation systems by using the spectral functional radiation. Hanamura (Tokyo Institute of Technology) (1) made spectroscopic experiments and calculations on spectral control' of emittance of rectangular microstructure cavities, (2) designed an experimental apparatus of nanogap generation by using evanescent wave, and (3) tried to actually fabricate GaSb photovoltaic cells in his laboratory. Yamada (Shibaura Institute of Technology) made spectroscopic experiments and calculations (1) on radiation emitted by the film type emitter and (2) on reflection of radiation of human skins. (3) He also tried to improve power conversion efficiency of a dye-sensitized solar cell. Less

热辐射是由材料中带电粒子的热振动产生的电磁波。它是工业上或自然上容易获得的能源。然而，它本身分散在一个覆盖普朗克分布的宽光谱区域，也是微弱的定向模糊辐射。因此，将其能量集中在某一特定波长（波段或区域），并像激光束那样发挥工程功能，往往是行不通的。本研究旨在开发控制热辐射的新技术，并将其转化为强调特定波段的光谱功能辐射。本研究以电磁波理论、光谱学、固体物理和传热科学与工程为基础，对光谱热工程进行了实验和理论研究，以期实现适用于能源工程和生命环境工程的硬件系统。具体而言，在2005-2007年的三年时间里，Makino， Wakabayashi和Matsumoto（京都大学）研究了(1)薄膜系统发射的热辐射球形波的干扰，(2)将球形波的电磁波理论与普朗克热辐射理论相结合的理论模型，(3)制备了薄膜系统型发射体。(4)研制了一种新型的、性能优良的宽光谱范围高速分光光度计系统，可同时测量表面的镜面反射率、半球面反射率和定向发射率的光谱；(5)在电磁波水平上实验验证了热辐射的Kirchhoffs定律。此外，牧野还以本课题导师的身份，积极在国内外热工程学术会议上作了多次全体会议、主题演讲和回顾演讲。Yoshida（京都大学）利用光谱功能辐射，热系统地考虑了热伏打和热光伏发电系统。Hanamura（东京工业大学）(1)对矩形微结构腔发射度的光谱控制进行了光谱实验和计算，(2)设计了利用倏逝波产生纳米间隙的实验装置，(3)在实验室尝试实际制造GaSb光伏电池。Yamada （Shibaura Institute of Technology）对薄膜型发射器发射的辐射和人体皮肤反射的辐射进行了光谱实验和计算。(3)他还尝试提高染料敏化太阳能电池的功率转换效率。少
