Using time resolved optical spectroscopy to understand excited state processes in materials.
Prof. Andy Monkman
Dept. of Physics, Durham University, England.
In this short course, I will describe various time resolved optical spectroscopy techniques and show how they are used to study excited states, excited state migration and energy transfer. Examples of studies in organic materials will be discussed, but the techniques are equally applicable to inorganic materials as well. I shall explain how you can observe non emissive or ‘dark’ states and various delayed emission phenomena. The time domain offers far more information to the spectroscopist than simple steady state measurements especially in differentiating emission or absorption from multiple excited states and energy transfer from one molecule to another, such as in Forster resonance energy transfer. Examples of the use of variable temperature with time resolved optical measurements will demonstrate the full power of optical spectroscopy to explain excited state photophysical properties of materials. Measurements from femtoseconds to seconds and all times in between will be described.
