| Outline of Annual Research Achievements |
We worked on various method to synthesize novel mesostructured perovskites (soft-template, microemulsion). He found that infiltrating perovskite within a pre-existing mesoporous structure was an effective way to restrain crystal growth and lead to fascinating properties. By synthesizing templates with various pore sizes (ranging from 3 to 7 nm), and infusing them with methylammonium lead halide perovskite precursors, he demonstrated how the optical properties could be tuned through composition and size control. He showed clear evidence of: i) anisotropic crystal growth along the channel direction, ii) quantum confinement, iii) ion mobility restriction and iv) possible photoannealing mechanisms.

| Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
He successfully carried out additional works as well.
|
| Strategy for Future Research Activity |
In the next year, the method developed in this year will be applied to other mesoporous templates to prepare perovskite composites.
