Ultraviolet-visible spectroscopy tests examine the absorption or reflective spectroscopy of a material over the ultraviolet-visible spectral region. The test itself bombards a sample of a material with light of varying wavelengths in a spectrophotometer, as it’s exposed to different light the spectrophotometer monitors the intensity at which the sample absorbs (or reflects) the light at these different wavelengths. And with the help of logging software it can produce spectral readouts like the one below:

UV-Vis spectroscopy tests could be performed after the synthesis of the CdSe Ink described in the sections above. And the desired result would be like the spectrogram above, where most light is absorbed either in or close to the UV spectrum and the intensity of light absorbed dropped significantly. This test needs to be performed on the ink to be used before printing to ensure that is capable of catching and using sunlight.
