[Solution]

The charged particle detection material and the charged particle detection film according to the present invention contain at least one of a fluorescent substance, a luminescent substance, an electroluminescent substance, a fractoluminescent substance, a photochromic substance, an afterglow substance, a photostimulated luminescent substance and a mechanoluminescent substance and can easily detect emission or incidence of charged particles in real time.

An inflatable sports ball is provided. The sports ball includes an interior bladder and a cover disposed about the interior bladder. The cover may include an outer substrate and an intermediate structure. The cover may further include an outer substrate surface, defined by the outer substrate, and a feature surface radially spaced apart from the outer substrate surface. Together the outer substrate surface and the feature surface cooperate to define an exterior surface of the cover. A mechanoluminescent material may be embedded in a portion of the cover. The mechanoluminescent material may be disposed at only one of the outer substrate surface and the feature surface, such that it is positioned to form a predetermined design on the cover. The mechanoluminescent material emits visible light in response to an externally-applied stress, such that the predetermined design illuminates when an external stress or mechanical stimulus is exerted upon the cover.

An exemplary vehicle assembly includes, among other things, a brake component configured to emit a first emission, and an indicator adjacent the brake component. The indicator includes a semiconductor layer configured to absorb the first emission and emit a second, different emission. An exemplary vehicle illumination method includes, among other things, absorbing a first emission with a semiconductor layer of an indicator. The first emission is emitted from a brake component. The method further includes emitting a second, different emission from the semiconductor layer.

Triboluminescent materials that produce light emission in response to mechanical action attract significant interest due to their wide range of potential utilization for mechanoresponsive sensors, light emitting devices and stimuli-induced glowing fibers, dyes, particles, paste, and films, etc. Here, we would like to disclose a general method of generating triboluminescent polymer materials blended with wide range of luminophores that emit light in response to mechanical action emitting light in a wide range of spectrum. The light generation is achieved via a non-destructive method even in the absence of direct contact with the polymer (e.g. through the layer of another polymer). Biocompatible luminophores can be easily utilized. Light emission is also observed under dry air.

A method of using a paint sensor to observe stress distributions of a stressed substrate includes the steps of applying a composition including a paintable medium and a mechanoluminescence material to a substrate, allowing the composition to form a solid film on the substrate, allowing the substrate to be stressed following the formation of the solid film, and measuring the stress the substrate has undergone by determining the mechanoluminescence of the solid film. A composition for visualizing stress or crack distributions includes a paintable medium and a mechanoluminescence material dispersed therein.
