| Research Abstract |
We successfully measured mechanoluminescence from a single mechanoluminescent (ML) nanoparticle. In order to measure the weak light emission from single ML nanoparticles induced by the application of a microforce, we developed an apparatus based on atomic force microscopy equipped with a photomultiplier. Interestingly, the emission intensity from the single ML nanoparticle was approximately proportional to the load applied by the atomic force microscope cantilever. These results indicate that individual ML nanoparticles show promise for use as nanoscale stress sensors and ubiquitous light sources in nanoscopic dark-field such as bio-tissues.
