| Outline of Final Research Achievements |
We have successfully developed the functional materials with mechano-electro-optoelectronic conversion. This unique property offers the advantages of wireless detection and nondestructive analysis, making it a promising candidate for various applications, such as stress sensing and damage diagnosis, and in particular for immediate in situ dynamic visualization of stress distribution in industrial plants and buildings. Using ferroelectric matrix with lanthanide ion doping, we have achieved high-performance mechano-electro-optoelectronic conversion. This unusually mechano-electro-optoelectronic conversion is attributed to the enhancement of a radiative recombination of carriers near the lanthanide ion sites under mechanical stimuli. The present discovery provides new research opportunities, not only for exploring piezo-photonic material, but also for applying stress-sensing devices.
