    Abstract: This paper discusses the excitation processes of a dye doped into an amorphous material as studied by using the photochemical hole-burning (PHB) technique. Our system is sulfonated tetraphenylporphin doped into poly(vinyl alcohol). The observed data were the extents of laser-induced hole filling (LIHF) in PHB at 20 K for wavelengths longer than the wavelength of the newly burned hole. Quantitative analysis using the least-squares method showed that the measured extents of LIHF can be explained by system parameters expressing non-site-selective excitations: the Debye-Waller factor, the energy of lattice vibrational excitation accompanied by the purely electronic excitation, and other parameters related to two kinds of vibronic excitations.

    Relationship between Molecular Structure of a Doped Dye and the Extent of Laser-Induced Hole Filling in Photochemical Hole-Burning

    Abstract: This paper reports that the extent of laser-induced hole filling (LIHF) in photochemical hole burning (PHB) is related to the molecular structure of a doped dye. We measured the extent of LIHF for disodium mesoporphyrin (MPS) doped into poly(vinyl alcohol) (PVA) at 20 K, and found it to be smaller than for sulfonated tetraphenylporphine (TPPS) doped into PVA at 20 K. The MPS molecule is flatter, lighter, and more rigid than the TPPS molecule. These features decrease the number of energy levels in the ground state S 0 and in the electronically excited state S 1 of the dye, resulting in an increase in the site-selectivity in PHB. This causes the smaller extent of LIHF for the MPS system.
