Luminescence is a type of photoluminescence \u2013 a phenomenon where a material absorbs energy under optical radiation and then emits part of that energy as visible light. When the energy supply stops, the material will continue to emit light at a certain level and for a certain time. This property, called remanence, depends on several parameters: dose received (energy x exposure time), spectral response of the material, and spectral distribution of the radiation received.
The applications of luminescence are wide and varied: watchmaking and luminous dials, signaling and security, marking and tracking, medical imaging, etc. These applications have various requirements, some of which must meet regulatory or normative requirements such as the ISO standard 17398<\/a>. Also, it is important to be able to precisely characterize the afterglow of objects loaded with phosphorescent material.
Drawing on our expertise in luminescence, optical metrology, and the design of LED lighting systems (ultraviolet, visible, infrared), PIS\u00c9O\u2019s experts have designed and created a test bench to characterize the luminescence of samples of different types and sizes, whose varied uses provide for exposure to daylight. This test bench, which integrates a video-luminancemetry camera and a multi-spectral illuminator, is currently equipped in the PIS\u00c9O laboratory<\/a>. It makes it possible for us to characterize customer samples in the form of a service. The bench can also be replicated or adapted for any customer who would like one.<\/p>\n\n\n
