Phosphorescent materials have the particularity of emitting light during a period of time which depends on their nature and duration of exposure to light radiation.
PISEO has test facilities to characterize the luminance, its decreasing over time, the persistence time, the spectral composition and the color of products incorporating phosphorescent materials (textiles, paints, concretes ...).
These characterizations allow PISEO's customers to know precisely the performance of their products and thus to value them.
