Abstract : This report presents the progress we have made on the project Determination of multi-photon absorption spectra: a comparison between transmittance change and fluorescence methods, and refers to the period from November/2013 to February/2015. Initially we present new results on the two-photon absorption cross-section of a specific platinum acetylide complex. Then a summary of the 2PA studies in the whole family of platinum acetylide complexes, investigate during this period of three years is presented, as well as a comparison between Z-scan and fluorescent methods to obtain the 2PA spectra. Finally, the three-photon absorption spectrum of the platinum acetylide complexs is presented and discussed.
