Answer:

Instead, they produced a colorful glow discharge (as in a modern neon light), caused when the electrons struck gas atoms, exciting their orbital electrons to higher energy levels. The electrons released this energy as light. This process is called fluorescence.Actually the thing is pure zinc sulfide doesn't show flourescence,but it fluoresce due to presence of cadmium and silver impurities. These impurities are mixed into zinc sulfide lattice.
