摘要: Abstract Saturation of the luminescence phosphors under stationary cathode-ray excitation is due to activator ground-state depletion and an increased importance higher order recombination processes at high density. A method based on model considerations presented determine kinetics dominating superlinear energy-loss process. The illustrated analyse saturation Zn 2 SiO 4 :Mn blue 5 D 3 → 7 F emission Y Al O 12 :Tb. Quadratic related excited ions (Mn, Tb) are found. With this result emitted optical flux conditions rise time decay can be quantitatively interpreted. When occurs excited-state absorption cannot excluded.
