Light absorption and emission are important concept to understand photochemistry. In this course, we learn about light and its interaction with molecules. Former part of this course is about emission from high temperature, light, and chemically excited states. Inorganic materials are also described not only for organic molecules. Mechanism of laser also described in order to apply for measurements and reactions. Latter part of this course is about 'photophysical process and photochemical process', 'photochromism' and 'refractive index.'
This course is for the students without back ground of photochemistry and photo physics. Knowledge and ability acquired through this course will help students enjoy photochemisty and photophysics in the future.
By the end of this course, students will have the following abilities:
1) To explain principles and applications of luminescent mechanism.
2) To explain principles of laser.
3) To explain Jablonski’s energy diagram.
4) To explain photochromism and photochromic molecules.
5) To explain relationship between molecular structure and refractive index.

|✔ Specialist skills||Intercultural skills||Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
At the beginning of each class, the previous lecture is reviewed. At the end of class, contents of the lecture is summarized. 'Required learning' is needed to be completed outside of the classroom for preparation and review purposes.
