    Near-infrared two-photon absorption and excited state dynamics of a fluorescent diarylethene derivative

    Near-infrared two-photon absorption and excited state dynamics of a fluorescent diarylethene (fDAE) derivative were investigated by time-resolved absorption and fluorescence spectroscopies. Prescreening with q...

    Photosynergetic Effects on Triplet–Triplet Annihilation Upconversion Processes in Solid Studied by Theory and Experiments

    Utilization of high density of triplets is important to overcome the dissipation of excitation energy. Triplet–triplet annihilation (TTA) has attracted attention to overcome the conventional limitation for the...

    Enhanced phosphorescence properties of a Pt-porphyrin derivative fixed on the surface of nano-porous glass

    The room-temperature phosphorescence chromophore, Pt(II) coproporphyrin I (PtCP), was fixed on the surface of a 3D-network of nanoscale pores of porous glass through ion-exchange reaction. The absorption and p...
