摘要
This paper reviewed the advances in fluorescent SiC codoped with nitrogen, boron and aluminum dopants applied to optoelectronics in recent years. The progress aspects in research of the fluorescent property, recombination theory, experiment, and construction design were discussed. The advantages that fluorescent SiC based white LEDs compared with conventional white LEDs were analyzed. It was confirmed that fluorescent SiC is a promising material to replace phosphor in the luminous field. Finally, the problems in the study of fluorescent 4H-SiC were pointed out.
