説明:

Opal photonic crystal films are based on closely-packed colloidal crystals deposited as thin layers on flexible plastic sheets. They can be used as simple and low-cost devices for visualising deformation, strain, cracks, defects, etc. Such opal photonic films were developed and manufactured at the National Institute for Materials Science (NIMS), Japan, and samples were provided to Canadian Nuclear Laboratories (CNL) for evaluation. Properties of the opal photonic films, together with some approaches for using these devices for non-destructive testing (NDT) of concrete, will be presented and discussed.
