Description
The first book devoted to a systematic consideration of electronic excitations and electronic energy transfer in organic
crystalline
multilayers and organics based nanostructures(quantum wells, quantum wires,
quantum dots, microcavities). The ingenious combination
of organic with inorganic materials in one and the
same hybrid structure is shown to give qualitatively new opto-electronic phenomena,
potentially important for
applications in nonlinear optics, light emitting devices, photovoltaic cells, lasers and so on. The book will
be useful not only
for physicists but also for chemists and biologists.To help the nonspecialist reader,
three Chapters which contain
a tutorial and updated introduction to the physics of electronic excitations in organic
and inorganic solids have been included.
Audience
Physicists, chemists and biologists - researchers, graduates and undergraduates.To help the nonspecialist reader, three Chapters which
contain a tutorial and updated introduction to the physics of electronic excitations in organic and inorganic solids have been included.
Contents The possibility of growing tailor-made systems incorporating in different ways organic crystalline materials , eventually joined to inorganic
heterostructures, has opened a new field of research in fundamental and applied physics. This is the first book devoted to a systematic
study of electronic excitations and energy transfers in such materials. The book can be useful to physicists interested in material science
and to chemists and biologists as well.
After three initial Chapters which contain a tutorial and updated introduction to the physics
of electronic excitations in organic and inorganic solids, multilayer organic structures and organics based heterostructures are considered.
In the first class of materials the role of quasi two-dimensional effects at surfaces and interfaces is described. "The Fermi Resonance
Interface modes", and the related bistability and multistability in the energy transmission through the interface are investigated,
as well as Frenkel excitons and charge-transfer excitons in organic multilayers and at donor-acceptor interfaces. Phase transition to
the conducting state (cold photoconductivity) and exciton-polaritons in organic microcavities with crystalline and disordered organics
are also discussed..
In the materials which result from the combination of organic and inorganic matter in a single hybrid nanostructure
(quantum wells, quantum wires, quantum dots and microcavities) new peculiar excitations which share properties of Frenkel excitons(large
oscillator strength) and of Wannier excitons (large radius) are shown to arise for strong coupling and to give rise to large enhansments
in the nonlinear optical effects . Such hybrid excitons are also discussed in the case when the organic-inorganic layers are inbedded
in a microcavity and hybridization is produced by the cavity electromagnetic field instead of Coulombic dipole-dipole interaction.
The performance of opto-electronic devices in planar microcavity structures are described in the book, in connection with experiments
which demonstraite a giant Rabi splitting in organic microcavities and polariton relaxation strongly affecting absorption , transmission
and luminescence.
In the case of weak resonance coupling between Wannier excitons in inorganic nanostructure and Frenkel excitons in
the organic overlayer a fast energy transfer from the first to the second is shown to occur, with subsequent strong luminescence. As
a consequence new concepts for light emitting devices can be developed and are described in the book. The energy transfer is also considered
when the organic and inorganic nanostructures are imbedded in one microcavity or in two interacting microcavities, in which case the
energy transfer between the donor and the acceptor nanostructures is greatly enhanced by the cavity electromagnetic interaction. The
role of the acceptor absorber and of different dissipative processes is analyzed in detail, in connection with recent experiments.
