When the electron falls back to its normal state, some of the energy is shed in the form of heat. When the UV light wave is reflected back to the human eye, it now has actually much less energy, therefore a much shorter wavelength. This wavelength is in the variety that we can check out. The end result being, you cannot check out the majority of the light coming from the resource, however you have the right to view its reflection off of objects containing phosphors.
