For almost a century, ultraviolet (UV) radiation has been used in hospital and industrial settings for the decontamination of surfaces, air, and water. UV spectrum can be divided into UVA (315–400 nm), UVB (280–315 nm), and UVC (100–280 nm), whereas the latter exhibits the strongest antimicrobial properties due to its absorption by

These plastic items become degraded by heat, UV light, oxidation, mechanical action, and biodegradation by living organisms like bacteria. These processes yield increasingly small particles that
Most acrylic plastics will allow light of wavelength greater than 375 nm to pass through the material, but they will not allow UV-C wavelengths (100–290 nm) to pass through. Even very thin acrylic sheets of less than 5 millimeters (mm) do not let UV-C light penetrate. Therefore, you will not be able to use standard acrylic plastic for your
does plastic absorb uv light
The short wavelengths of UV light typically absorb and scatter much more than visible or IR light. Surface imperfections such as scratches and pits are amplified under UV light and even the smallest surface flaws can be points of absorption or scatter, reducing system throughput.

Such pristine films can absorb UV light from the UV-A and certain UV-B wavelengths when doped with a moderate amount of nanomaterials (Rhim & Kim, 2013, pp. 413–442; Singh et al., 2021) (Fig. 6 a). As nanomaterial concentrations increase; they are likely to absorb the most light in the UVA and UVB regions.

2. When a photon interacts with an atom, three things can happen: elastic scattering, the photon keeps its energy level and changes angle. inelastic scattering, the photon keeps part of its energy and changes angle. absorption, the photon gives all its energy to the absorbing atom, and the photon ceases to exist.
