摘要: The linear and nonlinear fluorescence spectra of 5-(9-anthryl)-3-(4-nitrophenyl)-1-phenyl-2-pyrazoline (ANPP) have been studied in different polarity solvents. spectrum ANPP has two emission bands originating from the anthryl pyrazoline moieties on excitation at 355 nm. two-photon three-photon these are observed simultaneously when is excited 1064 nm due to proximity absorption λ/3 λ/2 exciting wavelength. similar structure indicates that originates same relaxation process.
