Our laboratory deals with ‘Phosphors’. Phosphors are light-emitting materials applied to light-emitting devices such as LEDs and play an important role in determining device performance. The luminescence color and efficiency vary depending on the combination of elements as well as the fabrication method, so we may be able to surprise the world with our ideas. Of course, we also carry out evaluations and learn about various optical and physical properties. And above all, we have a teacher who discusses the results properly. It’s hard to follow the professor’s arguments, but a great learning experience.
