What is "Fluorescent Brightener" - Definition & Explanation

A substance that is added to a textile (uncoloured or coloured) to increase the apparent light reflectance in the visible region by the conversion of ultraviolet radiation into visible light and so to increase the apparent brightness or whiteness of the textile.
Fluorescent brightening agents or optical brightening agents or fluorescent whitening agents are dyes that absorb light in the ultraviolet and violet region of the electromagnetic spectrum, and re-emit light in the blue region.
