When violet-blue laser light is incident upon all of the papers and plastics, there is some fluorescence. The violet laser incident on the red paper(Row 1 in Table I) reflects back a bright reddish dot: this is the combination of the continuous emission, which is stronger on the long wavelength end than the short wavelength. You can also see that a very weak discrete violet-blue diffraction dot from the portion of laser light is reflected on the far left end of the spectrum The yellow paper(Row 2 in Table I) plastic reflects almost no violet-blue light, and the fluorescence spectrum ranges from a small amount of blue to red, which makes the resulting dot greenish-yellow in color. Violet-blue laser light on orange paper(Row 3 in Table I) and orange plastic(Row 4 in Table 1) papers produce, again, a weak violet-blue dot and a continuous spectrum. that contains all the colors of the rainbow, which results in a yellowish white dot. The pink paper(Row 5 in Table I) and the pink plastic(Row 6 in Table I) reflect different shades of magenta since the fluorescence spectrum contains predominantly blue and red emissions. When incident on the green paper(Row 7 in Table I), the violet-blue light appears cyan since the fluorescence spectrum is strongest in the cyan, green, yellow spectral region. On the green plastic(Row 8 in Table I), the violet-blue laser dot appears green due to the fluorescence spectrum missing a large portion of violet, blue, and red light. Finally, violet-blue laser light on blue plastic(Row 9 in Table I) yields a blue dot and a weak fluorescence spectrum that is just barely visible in the image.
