Paper brightness is typically measured at 457 nm, well within the fluorescent activity range of brighteners.

Some non-stilbene brighteners are used in more permanent applications such as whitening synthetic fiber.

The phenyl and indole chemical moieties in proteins absorb UV, and are made visible by blocking the fluorescence of the material beneath them—often UV brighteners in fabrics.

These modules have a transparent ( quartz ) window on the top of the chip that allows the UV radiation in. Fluorescent dye uses Colorless fluorescent dyes that emit blue light under UV are added as optical brighteners to paper and fabrics.
