摘要：

We report pulsed laser studies of nonlinear luminescence in a platinum ethynyl complex which, from 560 to 700 nm, shows strong two-photon absorption from the ground singlet state to an excited singlet state. The spectral dependence of the photoluminescence peaks indicates that in the region from 560 to 700 nm the two- photon absorption cross section is independent of excitation wavelength. Through the use of a simple calibration we have been able to estimate the number of states (N-S1) formed from two- photon absorption, and have found good agreement with theory using the value of beta = 0.34 cm/ GW measured previously.
