The Report on Unidentified Flying Objects In the latter case the phenomenon is essentially the same as fluorescence, in which the dark rays of the solar spectrum beyond the violet are made visible. Young Folks' Library, Volume XI (of 20) Wonders of Earth, Sea and Sky He said within himself: "Why not pass the X-rays through the object to be inspected and then convert them into visibility, as if by fluorescence." Notable Events of the Nineteenth Century Great Deeds of Men and Nations and the Progress of the World There are many ways of exciting phosphorescence and fluorescence, the latter being merely an unenduring phosphorescence, which ceases when the exciting energy is cut off.
