Abstract

A new ligand, 4-dipropylaminobenzaldehyde thiosemicarbazone (HL) and its complexes (ZnL2, CdL2), which exhibit intense two-photon excited (TPE) dual fluorescence using 800 nm laser pulses in the femtosecond regime, were synthesized and fully characterized. The measured power dependence of the fluorescence signals provides direct evidence for TPE. The two-photon excited dual fluorescence spectra were compared and contrasted with the ...
