Detonation nanodiamonds as UV radiation filter

The attenuation of ultraviolet radiation (UVR) by detonation nanodiamonds (DND) can be significant, depending on the concentration, composition of DND surface, size of DND particles and content of nitrogen defects in DND. The ability of DND to attenuate efficiently UVA (320–400 nm), UVB (290–320 nm)...

Description
Summary:The attenuation of ultraviolet radiation (UVR) by detonation nanodiamonds (DND) can be significant, depending on the concentration, composition of DND surface, size of DND particles and content of nitrogen defects in DND. The ability of DND to attenuate efficiently UVA (320–400 nm), UVB (290–320 nm) and UVC (190–290) radiation via absorption and scattering makes them attractive broad-spectrum UV-protecting agents. The studied DND exhibited red photoluminescence presumably due to the nitrogen-vacancy centers.
