11. He discovered the phenomenon of progressive phosphorescence . 12. "' Phosphorescence "'is a specific type of photoluminescence related to fluorescence. 13. S 0 transition occurs ( also delayed ), and corresponds to the phenomenon of phosphorescence . 14. It is dimly lit by a mysterious phosphorescence known as the " death-fire ". 15. In other words, it gives off visible light through fluorescence, phosphorescence , or radioluminescence. 16. Phosphorescence is based on this principle.17. In 1910, discovered the phenomenon of progressive phosphorescence in the phosphorescence spectra of organic molecules. 18. In 1910, discovered the phenomenon of progressive phosphorescence in the phosphorescence spectra of organic molecules. 19. The radiative decay from an excited triplet state back to a singlet state is known as phosphorescence . 20. I know that these type of lamps emit phosphorescence for a while after it is switched off.
