From Basic Principles to Applications<br><br>
</b></font></div>
Abstract:<br>
The talk concentrates on the luminescence detection of single quantum
objects such as organic molecules and semiconductor nanoparticles
(quantum dots). In the first part the principles of this ultrasensitive
detection scheme in combination with optical spectroscopy will be
outlined.<br>
The following applications will concentrate on <br><br>
"<x-tab> </x-tab>molecular
probes for diffusion on surfaces and in very thin liquid and polymer
films<br>
"<x-tab> </x-tab>
photoinduced charge transfer processes in nanoparticles and <br>
"<x-tab> </x-tab>formation
of organic-inorganic nanoassemblies.<br><br>
