摘　　要：A new ligand, 10ethylphenothiazinyl 3 yl methylene thiosemicarbazon (HL) and its complexes ML2 (M=Zn2+, Cd2+), which exhibit intensive two-photon excited (TPE) fluorescence at 800 nm laser pulses in femtosecond regime, were synthesized and characterized. The measured power dependence of the fluorescence signals provided direct evidence for TPE. All of them exhibited a large two-photon absorptive cross section and, more importantly from the application point of view, high photochemical/photothermal stability.A new ligand, 10ethylphenothiazinyl 3 yl methylene thiosemicarbazon (HL) and its complexes ML2 (M=Zn2+, Cd2+), which exhibit intensive two-photon excited (TPE) fluorescence at 800 nm laser pulses in femtosecond regime, were synthesized and characterized.
