Abstract
Concentration-dependent nonlinear absorption and radiative up-conversi on effects have been investigated in aluminosilicate sol-gel materials containing the sodium salt of tetra-4-sulfonatophenylporphyrinatocopp er (II). The observed phenomena are attributed to excited-state absorp tion events in both doublet and quartet manifolds. Intensity-dependent saturation effects are described.
