Influence of the experimental parameters on time-resolved transient hole-burning (original) (raw)
1990, Chemical Physics Letters
The influence of the burning power, burning time and probe power on the holewidth, hole depth and hole decay time have been studied in time-resolved transient hole-burning (THB) experiments. The systems investigated are free-base polphin (HI,P) in crystalline n-octane (n-C,), zinc-porphin (ZnP) in n-Cs, and ZnP in amorphous polyethylene (PE). The THB kinetics is interpreted in terms of saturation broadening due to a triplet state bottleneck. The holewidtb and decay time of the hole arc not influenced by the probe power, FJA, at least for P,/A< 10 pW/mm'. The same hole-broadening kinetics has been found to apply for the crystalline and the amorphous hosts here studied.

Effects of dispersive burning kinetics on hole-burning spectrum in dye-doped polymers
Chemical Physics Letters, 1988
The profile of the burnt zero-phonon hole, as well as the time dependence of the hole depth, has been measured at 2 K for rhodamine 640 in a polyvinyl alcohol film by means of a highly sensitive spatial-modulation technique. The result is well explained by a dispersive first-order reaction model in which the homogeneous width of the zero-phonon line and the finite spectral width ofthe laser light are taken into account. It is shown that the dispersive burning kinetics causes not only the non-exponential hole growth but also on the time-dependent spectral broadening of the burnt hole.
Temperature-dependent kinetics of photophysical hole burning in a tetracene-doped mthf glass
Chemical Physics Letters, 1986
hole burning in a MTHF(TC) glass follows the concept of decoupled first-order reactions with Gaussian distribution of the tunnelling parameter. The decrease of the hole-burning yield with increasing temperature signals thermally activated hole refilling in the excited state. The ratio of TLS states responsible for dephasing and hole burning, respectively, is estimated to be = 10'.

Dispersive hole growth kinetic data obtained with bum intensities in the nW to pW/cm' range are reported for the laser dye oxazine 720 in glycerol glasses and polyvinyl alcohol polymer films. The data are well described by a theory that employs a distribution function for the hole burning rate constant derived from a Gaussian distribution for the tunnel parameter of extrinsic two-level systems. The linear electron-phonon coupling is taken into account in the analysis. An approach for calculating the nonphotochemical hole burning quantum yield as a function of the hole depth is described. Deuteration of the hydroxyl proton of the amorphous hosts reduces the average hole burning quantum yield by a factor of = 20, indicating that large amplitude motion of this proton is an important component of the tunneling coordinate. Temperature-dependent data are used to prove that the dispersive hole burning kinetics are independent of temperature between 1.6 and 7 K (the range studied).
Room-temperature microparticle-based persistent hole-burning spectroscopy
Journal of the Optical Society of America B, 1992
We present an analytical model for hole burning in a random collection of microparticles, based on singleparticle properties. The model indicates that the linewidth of the central hole is approximately Lorentzian in shape and is controlled by the photon lifetimes in individual particles. Our conclusion is consistent with experiments on a two-dimensional layer of connected microparticles. Electrodynamic calculations for a pair of particles in contact provide an explanation for the apparent lack of importance of interparticle interactions in the experiments and suggest conditions under which the effects of such interactions should appear.
Low-temperature spectroscopy of organic molecules in solids by photochemical hole burning
Applied Physics B Photophysics and Laser Chemistry, 1982
Characteristic features of photochemical hole-burning (PHB) in the impurity spectra of low-temperature solids and PHB applications in molecular spectroscopy are considered. The evolution of a no-phonon hole and a phonon sidehole in excitation and fluorescence spectra is analysed on the basis of model calculations. Some more complex models for PHB are considered , which take into account reverse reactions, the optical thickness of the sample, the inhomogeneous dispersion of both homogeneous linewidths and transition energies of the photoproduct and quasi-static impurity-impurity interactions. The effects of PHB on fluorescence line narrowing are discussed. By PHB homogeneous linewidths of purely electronic and vibronic no-phonon lines in the spectra of some porphine and phthalocyanine derivatives in various matrices are measured and their temperature dependence is studied. The latter is found to be essentially different in polycrystalline and glassy matrices. Line-broadening mechanisms are discussed. By PHB the existence of an inhomogeneous distribution of vibrational frequencies in molecular impurities is established. The applications of PHB in the studies of photochemical reactions in solid solutions of phthalocyanine derivatives and tetracene are regarded and the mechanisms of these reactions are discussed. The results obtained by PHB for chlorophyll and its derivatives are presented.
