【摘要】：近年來,不含金屬元素的聚合物氮化碳半導(dǎo)體以其獨特的材料組成和電子結(jié)構(gòu)特征吸引了研究人員的廣泛興趣,在諸如光催化、光致發(fā)光、光電化學(xué)等光激發(fā)相關(guān)領(lǐng)域具有潛在的應(yīng)用前景。聚合物氮化碳光激發(fā)過程由能帶結(jié)構(gòu)、載流子行為、激子效應(yīng)等因素所主導(dǎo),對于這一過程的研究在材料性能的優(yōu)化、應(yīng)用領(lǐng)域的拓展以及應(yīng)用機制的理解等方面具有重要意義。圍繞這一主題,本文綜述了近年來聚合物氮化碳材料光激發(fā)過程研究中取得的最新進展,簡單介紹了聚合物半導(dǎo)體光激發(fā)過程的研究方法,分別討論了光激發(fā)下材料中的載流子行為和激子過程,進而總結(jié)了常用改性策略對于材料光激發(fā)過程的調(diào)控機制,此外還對材料光響應(yīng)特性功能化的研究進行了概括。
[Abstract]:In recent years, metal-free polymeric carbon nitride semiconductors have attracted extensive interest for their unique material composition and electronic structure, such as photocatalysis and photoluminescence. The photoexcitation process of polymer nitride is dominated by energy band structure, carrier behavior, exciton effect and so on. It is of great significance to expand the application field and understand the mechanism of application. In this paper, the latest progress in the research of photoexcitation process of polymer carbon nitride materials in recent years is reviewed. This paper briefly introduces the research methods of polymer semiconductor photoexcitation, discusses the carrier behavior and exciton process of materials under photoexcitation, and then summarizes the mechanism of controlling the photoexcitation process by common modification strategies. In addition, the research on the functionalization of the material's light response is summarized.
