Brilliance usually refers to the light reflected by the facets of a gemstone such as diamond due to its high refractive index. Nowadays, high-refractive-index materials find application in many optical and photonic devices and are mostly of inorganic nature. However, these materials are usually obtained by toxic or expensive production processes. Herein, the synthesis of a thin-film organic semiconductor, namely, polymeric carbon nitride, by thermal chemical vapor deposition is presented. Among polymers, this organic material combines the highest intrinsic refractive index reported so far with high transparency in the visible spectrum, even reaching the range of diamond. Eventually, the herein presented deposition of high quality thin films and their optical characteristics open the way for numerous new applications and devices in optics, photonics, and beyond based on organic materials.
光彩通常是指由于钻石等宝石的高折射率，其刻面反射的光。如今，高折射率材料在许多光学和光子器件中得到应用，且大多为无机性质。然而，这些材料通常是通过有毒或昂贵的生产工艺获得的。在此，介绍了通过热化学气相沉积法合成一种薄膜有机半导体，即聚合氮化碳。在聚合物中，这种有机材料结合了迄今为止报道的最高固有折射率和在可见光谱中的高透明度，甚至达到了钻石的范围。最终，本文所展示的高质量薄膜沉积及其光学特性为基于有机材料的光学、光子学及其他领域的众多新应用和器件开辟了道路。
