大阪大学研究生院工学研究系材料生产科学专业教授藤原康文试制出了利用GaN系半导体的红色LED元件。利用GaN系半导体的蓝色LED元件及绿色LED元件现已达到实用水平,但试制出红色LED元件“还是全球首次”(藤原)。如果可与蓝色LED元件及绿色LED元件一样,利用GaN系半导体制造出红色 Osaka University Graduate School of Engineering Materials Science and Technology Professor Fujiwara Kang text trial production of GaN-based semiconductor using red LED components. Blue LED components using GaN based semiconductors and green LED components have now reached the practical level, but the trial of the red LED components “is the world’s first” (Fujiwara). If a blue LED element and a green LED element can be used, a red
