Triplet exciton transport in isotopic mixed naphthalene crystals. I. Kinetic analysis of trapping and fusion
Time-resolved triplet exciton transport in binary mixed crystals has been studied for CHin CloDg (20%-100%) at liquid helium temperatures. The delayed fluorescence decays ar~o g ~xponential and range from milliseconds to nanoseconds as Cg goes from 0.2 to 1.0. The analysis IS based on the presence of a BMN supertrap in large amounts (103) and on the fact that supertrapping.o~ th~ guest ex~itons...
متن کاملTriplet exciton transport in isotopic mixed naphthalene crystals . II . Master equation analysis
The experimental data on triplet exciton transport in isotopically mixed crystals of naphthalene/ perdeuteronaphthalene (paper I) are contrasted with singlet exciton transport in the same samples (20%-100%) and analyzed in terms of incoherent hopping models. The master equation approach is emphasized and extended. We modify the conventional continuum master equations via a physically plausible ...
متن کاملKinetic Transport in Crystals
One of the central challenges in kinetic theory is the derivation of macroscopic evolution equations—describing, for example, the dynamics of an electron gas—from the underlying fundamental microscopic laws of classical or quantum mechanics. An iconic mathematical model in this research area is the Lorentz gas, which describes an ensemble of non-interacting point particles in an infinite array ...

متن کاملMethod of Heavily Doped Isotopic Mixed Crystal for Determination of Exciton Splittings and Normal Modes: Raman Spectra of Naphthalene*
Recent developments on concentrated mixed crystal exciton spectra enabled us to develop new qualitative and quantitative criteria for the identification of vibrational exciton splittings: Observation of an appropriately structured spectrum in the exciton k7"'O gap. This is especially useful for Raman Spectra where the ideal mixed crystal approach is not very useful due to the low intensity of v...
